Discussing CEOs is completely missing the point. There are fewer than 2000 businesses in the entire country with more than 10,000 employees. Meaning fewer than 2000 CEOs of them.
The issues are that fundamentally capital naturally accrues capital - it's is not a stable equilibrium. Capital is sticky and pulls in other capital. The second is that when a country grows in productivity and wealth those gains go to some split of capital and to labor, and in the US for the past 55 years they have gone exclusively to capital.
To explain this, imaging there are two rooms, and everyone enters a room. The one on the left or the one on the right. You enter with the money you own. Then when inside each room, once a day you pick a number from 1-100 and get paid (or debited) based on the number chosen. The issue is the distributions in each room are different. In the room on the left, 70% of numbers pay a positive return based on what you brought in (the rest take money from you). In the room on the right, only 20% of numbers pay a positive return and it's a flat amount from the distribution.
People in the room on the left spend all this time discussing how they have the greatest picking strategy, and how much better they are at picking, when fundamentally the difference is that they're in the room on the left and that's the distribution where all the gains are.
And all of the above ignores the fact that you can split your wealth and use it to pick multiple numbers in the room on the left and so reducing your risk of losing overall, while the room on the right you have to pick one and bet it all on it.
The fundamental issue is that all income gains are going to capital, and not to labor. The end state of this is that most of the room on the right all goes bankrupt.
So why doesn't everyone everyone go in the room on the left? There is a daily fee to be alive and unless you have the wealth to start, even if you hit the best distribution in the left, you still won't have enough to cover the flat fee.
That gets you to the second issue. Investing in capital markets it's some genius plan that only wealthy people can think of. Fundamentally it's not all that different from sports betting or any of another different fields. Why doesn't everyone do it? Because only some people can afford to do so and get returns that are worth it. And people really underappreciate how little of a meritocracy it is.
Imaging you come up with a genius investing plan and manage to average 20% returns every year for 20 years. This is brilliant and almost impossible. But your initial investment is all you have: a single dollar. At the end of that period, you've got Someone else who does the exact same work, has the exact same insight, just as exceptional comes up with the same plan, but start with $1MM, and they end up with $40MM. Capital naturally accumulates. And money paid on capital is not due to additional effort, or harder work, or producing more value. Additional money is paid because in the beginning they had additional capital. It's that simple.
The idea that there is a meritocracy in capital investing is completely false. In the split between capital and labor, it is heavily weighed towards capital for 45 years and we're seeing the result of that. And within capital markets it's heavily weighted towards those with capital.
The overall most prosperous time in the US society was the period where there was the least income inequality. And that was intentionally instituted.
There are two "natural" states of wealth distribution. No private ownership / property - which means we're essentially back to hunter / gatherer states. Or aristocracy / 1% and almost everyone else poor. That's essentially been the state of the world for a couple thousand years. If you want any other wealth distribution in society (and I think most people do, and like the concept of social mobility), you need to include methods of enforcing it against the natural state of ultra wealth concentration.
Democracy is not the natural state of the world. We chose to enforce democracy against the natural state. Income distributions are also not a natural state, if we want there to be anything more than aristocracy and serfdom we need to ensure that as well.
