No matter what solution we chose, I cannot see any way to escape the fact that the population growth and automation will eventually produce a situation where there's simply not enough jobs for everyone who want to work. And then what? If we move everyone to universal income, what influence would it have on production of goods and the circulation of money? In other words, if a large part of the population doesn't work, where will the money come from? If we move everyone to part-time work, how would we earn enough to maintain our current lifestyle? After all, we cannot expect employers to pay full wages for part-time work. Wouldn't we require some sort of government support anyway then, just to survive?
