A simple thought:
In a liberal system everyone tries to make it on his own and some succeed and some don’t. A natural inequality emerges. But then something wonderfull happens:
Redistribution on the workfloor.
The people who make it, will own a company that is doing well. And in these companies everyone can go to work and earn a living. The big factories and office buildings of the mid 20th century were a great example of that. Some people started successful companies, but many were able to get a well paid job in those companies. They bought a house, went on holiday, and paid for a good education for their children. The company was the big machine of redistribution of the wealth: Money went from the wealthy boss to the poor working class. This was how the middle class got big.

But what if you have companies that don’t employ people, or very few? What if you have a company with a multimillion revenue and only 3 employees?
Do you still have a good redistribution of wealth?
Can we keep a middle class in the future?
What happens to the losers of the liberal system?
(The story of Instagram is famous for this type of company that was employ very few people: It was sold for a billion $, and at the time it had 13 employees.)
