How Wall Street Makes Money From Your Confusion
A map of where your money actually goes when you think you’re not paying for anything.
There’s a moment I think about a lot from my equity research days. I was sitting in a meeting with a senior salesperson who covered our institutional accounts, and he was explaining how the firm made money on a particular product. The structure was so complex that even after a 20-minute explanation, I had to ask him to walk me through it again. He laughed and said, “Yeah, that’s the point.”
I was 22 and I assumed he was joking, or being self-deprecating about an unfortunate quirk of how the product was built. He wasn’t. He meant it literally. The complexity wasn’t a bug in the design. The complexity was the design. If clients understood exactly what they were paying, they wouldn’t pay it.
That conversation rearranged how I see the entire financial services industry, and it took me years to fully metabolize. Wall Street doesn’t make most of its money from being smart about investments. It makes money from the gap between what you think you’re paying and what you’re actually paying. The wider the gap, the more profit there is in it.
Most of what I want to write about today is just the question of where that gap lives, because once you can see it, almost every confusing thing about the industry starts to make sense.
Most fees you pay are invisible by design
The defining feature of modern retail finance is that you almost never write a check. Your trading app is free. Your index fund’s expense ratio is deducted before performance is reported, so the number on your statement always looks like it captured everything the market gave you. Your bank account doesn’t charge a monthly fee as long as you keep enough money in it. Your robo-advisor charges a quarter of a percent, which sounds like a rounding error.
None of these are free. They’re priced into the product in ways you’d have to actively go looking for in order to find. Your free trading app gets paid by market makers to send them your orders. I wrote about that mechanic in detail in Free Trading Isn’t Actually Free, so I won’t redo the math here. The bank “free as long as you keep $5,000 in it” deal is the bank borrowing your $5,000 at zero and lending it back out at seven. The robo-advisor’s 0.25% fee sounds small until you realize the algorithm is also placing you in funds whose managers paid for shelf space, and nobody’s required to draw you a picture of why those particular funds got picked.
The thing all of these products share is that the fee never arrives as a fee. It arrives as a slightly worse price, a slightly lower yield, a slightly suboptimal portfolio construction. Each one feels like nothing in the moment. They’re not nothing. They’re the entire revenue model of a multi-trillion-dollar industry, and the reason you can’t feel them is that they were specifically engineered not to be felt.
Complexity is the actual product
Here’s the part that took me longest to internalize, even working inside the industry.
Simple financial products don’t make anyone much money, because simple products are easy to compare. If you’re choosing between two index funds that hold the same stocks, you’ll pick the cheaper one. There’s no margin to defend. This is why Vanguard exists at the scale it does and why the rest of the industry has spent forty years figuring out how to compete with it without competing on price.
The way you compete with Vanguard without competing on price is to sell something Vanguard doesn’t sell. Variable annuities with guaranteed minimum withdrawal benefits. Indexed universal life policies with cash value components invested in proprietary subaccounts. Structured notes tied to custom indices. Buffer ETFs. Defined outcome strategies. Every one of these has a real explanation, and every explanation is just complicated enough that two of them can’t be compared head to head. You can’t put two variable annuities next to each other and tell which one is cheaper, because the fee structures use different terminology and the underlying math is intentionally opaque.
That’s not an accident. That’s the moat. A product the customer can’t comparison-shop is a product the seller can charge a premium for, and the premium is the whole game.
I watched this dynamic play out at the firm where I worked. The simple, low-margin products had no internal champion because there was nothing in it for anyone to sell them. The complicated, high-margin products had dedicated sales teams, marketing budgets, conference sponsorships, dinners at Sparks. The economic gravity of the industry pulls in one direction, and it isn’t toward clarity.
The vocabulary gives it away if you listen for it. Anything described to you as “sophisticated” is being sold to you. Anything that requires a 30-minute conversation with a licensed professional to understand is a product where the 30-minute conversation is the sales process. Anything pitched as offering “downside protection” or “enhanced yield” or “tax-advantaged growth” through a structure you wouldn’t otherwise have access to is something where you are paying for the structure, and the structure is mostly there to justify the fee.
The compounding problem
The reason all of this matters, and the reason I keep writing about it, is that the cost of these invisible fees is not linear. It compounds.
A one percent annual fee on a portfolio sounds trivial. Over a single year, it is. Over thirty years of compounding, a portfolio paying one percent in fees ends up roughly a quarter smaller than the same portfolio paying nothing. That’s the rough magnitude. The exact number depends on returns and contributions and a dozen other variables, but the order of magnitude is correct, and it’s why I wrote a whole separate article about why a financial advisor is the most expensive purchase most people will ever make without realizing it. The fee feels small. The fee compounds against you for the entire time the money is invested. Those two facts together are the whole story.
Now stack the fees. The advisor charges one percent. The funds the advisor put you in charge another half a percent. The annuity your aunt’s friend sold you when you got married is charging three percent inside the wrapper. The trading app you use for your “fun money” account is shaving fractions of a cent off every order. None of these individually feels like much. Cumulatively, on a long enough timeline, they’re the difference between retiring comfortably and not.
I’m not going to put a specific dollar figure on it because I don’t trust the number I’d come up with, and I don’t think you should trust any specific number anyone else gives you either. What I trust is the direction. The direction is enormous, and it points away from you.
Why this is allowed to keep happening
It would be satisfying to say the financial industry is full of bad people doing bad things, and some of it would even be true. Mostly, though, it’s not. The people working at brokerages and fund companies and advisory firms are normal professionals who took the jobs that exist, and the jobs that exist are the ones the business model rewards. Nobody at a major firm is sitting in a meeting room cackling about how they’re going to fleece retail investors today. They’re just doing the job, and the job happens to be structured so that the harder you do it, the more wealth quietly transfers from people like you to people like them.
What’s actually changed in the last decade or so isn’t the industry’s incentives. Those have been the same for a hundred years. What’s changed is that for the first time, you have a clean way to opt out of most of it. A total market index fund costs three basis points a year. A self-directed IRA at a major broker costs nothing to open. A portfolio that beats roughly nine out of ten professionally managed funds over a 15-year period requires about two hours of setup and almost no ongoing maintenance. The exit door has been there the whole time, and in the last fifteen years, it got cheaper and easier to walk through than it has ever been in history.
What I actually do
For whatever it’s worth, here’s what my own setup looks like, because I think it’s useful to see how simple this can be when you stop paying tolls.
I have a brokerage account at a major low-cost broker. The core of my portfolio is in two index funds with combined expense ratios under five basis points. I don’t have a financial advisor. I have never owned a whole life insurance policy or an annuity, and I don’t expect I ever will. My emergency fund sits in a high-yield savings account paying ~4%. I check my net worth once a month, do a full review once a year, and otherwise don’t think about my money very much.
That’s it. The total annual cost of my financial life, all in, is somewhere south of $50. It has been the most boring financial system imaginable for years, and it has consistently outperformed every more complicated thing I’ve ever considered doing instead.
The senior salesperson who told me the complexity was the point wasn’t trying to warn me. He was just being honest about how the business worked.
What to Read Next
📖 The Simple Path to Wealth by JL Collins. The clearest argument I’ve ever read for ignoring almost everything the financial industry sells you and just buying low-cost index funds. If this article made you angry, this is the book that channels the anger into a plan.
📖 The Psychology of Money by Morgan Housel. Housel’s chapter on fees as the price of admission to a long-term return is the cleanest piece of writing I know on why we tolerate the cost structures we tolerate.
📖 Where Are the Customers’ Yachts? by Fred Schwed. Written in 1940 and still unsettlingly accurate. The title comes from a story about a visitor to New York being shown the bankers’ and brokers’ yachts and asking, innocently, where the customers’ yachts were. That joke has been the business model for almost a century.
📖 Liar’s Poker by Michael Lewis. Lewis’s account of his time at Salomon Brothers in the 1980s remains the funniest, most damning portrait of how Wall Street talks about retail customers when retail customers aren’t in the room. The decade is different. The tone is exactly the same.
🎧 All four are excellent on Audible. The free trial gives you one credit to start, and Liar’s Poker is the one to spend it on. Lewis’s deadpan reads beautifully out loud.
