First, I'm assuming that you are not a free market maximalist, and that you believe that a market without any regulation will result in mega monopolies where it no longer matters if you find the price of the product to be fair.
The distribution of the wealth created by the massive increase in productivity has been trending towards the organisational top for many decades now.
I don't think that the management has gotten exponentially more efficient and better at their job to justify their increasingly bigger share of the profits.
Wealth isn't distributed in a free market, it is created.
That's not your determination to make. Other people, obviously, disagree. I think capital has been the primary driver of the increase in productivity. So it's sensible that a larger share of the gains go to that.
Nitpick: There's no such thing as a "market with any regulation," because regulation is what creates markets in the first place, by making most unsavory forms of profit illegal, in order to incentivize people to innovate and create.
If you only look at nominal dollars, you could say the wealth has trended toward the top. But the average person is materially richer today than at pretty much any point in the past, in terms of real income + real consumption + net worth + access to goods and services adjusted by quality + safety. There's a lot to be happy about, and I know few if any people who'd rather go back in time and live a worse life just so they're part of a time period where inequality is less.
Also, inequality has always been high throughout human history. The brief period of time in the mid 20th century where things seemed a bit closer, was the exception, not the rule, as far as I understand.
And again, if you only look at nominal dollars, maybe inequality seems extreme. But thanks to technology, the actual lived experience and quality difference between middle and upper classes is lower than it's ever been. What exactly is Bill Gates doing in his day-to-day life that's so much higher quality than what the average American is doing? He's eating the same burgers, wearing the same clothes, driving on the same roads, consuming the same entertainment, and getting more-or-less the same healthcare. His improvements on these things are incremental at best.
Compare to the gap between the rich and poor at any other time in history, and it's miniscule today. Housing and education and healthcare, imo, are the real areas to focus on the most. And I'm a big believer in raising the floor. But lowering the ceiling just so you can say things are more equal in nominal dollars isn't going to help anyone.
