We have set our laws so that a single person (or family) owning a company is a very risky proposition and our culture has encouraged people to have zero loyalty to their employees or, conversely, their employers.
Additionally, we have set our tax laws such that you make money by increasing stock price, not paying an income from that business ownership, leading to investments towards larger, more valuable companies rather than long term returns (dividends.)
We have a law and culture problem.
"Capitalism" or "free markets" is neither moral nor immoral, but we surely don't have "unfettered" free markets. We have distorted markets and we are seeing the consequences of that distortion. (We also have entrenched bureaucracies and interest groups, which further distort the "free market".)
What we have is too much government and not enough resistance to its pernicious influence by the culture.
Things have changed. One hundred to one hundred fifty years ago, the great robber barons of American industry were (I think without doubt) capitalists. They set out to make money -- lots of money. They did that largely by making and selling things. To make more of those things, they employed more workers. I grew up in New England, and I'm an architect with some peripheral education in city planning. New England mill towns still have rows and rows of identical houses near the old factories and mills. These were worker housing -- they were houses built by the capitalist pig robber barons to house the people who worked in their factories. The pay wasn't enough to make the factory workers rich -- they weren't going to be vacationing in Monte Carlo on factory wages, but they had a living wage, and they had a decent roof over their heads. Courtesy of the big man in the big house.
Sam Colt is a good example. The area around the old Colt factory in Hartford, Connecticut, is still known as Coltsville. It was a neighborhood made up entirely of Colt factory worker housing.
The problem today isn't capitalism,
per se, it's the shift in outlook and ownership. "Back in the day," the goal was to build up the company, which led to more jobs. Today, the trend is for the hedge funds to buy viable companies, milk all the capital out of them until they are no longer viable, then dump them. The fault, IMHO, can't be laid at the feet of "capitalism." The fault lies with greed, and with a system that rewards CEOs for destroying companies rather than building them up.
