Could also be possible today, but we chose a capitalistic system that leads to an increasing wealth gap. And now we're in a situation where the richest 1% own 50% of the wealth.

So, if we increase automation and the ownership structures stay the same, this inequality will get worse, not better.

Nope. If everything is totally automated, if ever, the gap between the rich and the poor will widen even more. Most people will live in misery while only a handful of people enjoy all the automation.
