How much free time would we have now if the current gains from capitalism were evenly distributed (or any previous economic system)? What makes you think automation will be different?

- 1% of the world population owns 95% of the total world wealth, as per Oxfam - World Food Program from the UN calculated a need to 93 billion per year to solve food hunger in 5 years - A single SpaceX IPO already raised 85$ billion of cash

I would say... a lot.

After indeed, maybe without capitalism we would have not got this amount of wealth already, and nothing stops us to build socialism inside a capitalistic system, by using more cooperative, governement venture capitals, sovereign funds.
