> This comment naively believes in zero sum creation of wealth.

As long as we're in a capitalist society, wealth is certainly zero-sum.

Every technological advancement that made jobs easier just allows corporations to increase their margins or increase the workload. If I automate some of my work and now only need to work 20 hours/week, I don't get 20 more hours/week of free time, I'm just given more work to do.

If someone gets completely automated out of their job, they don't get to relax and enjoy free time. They have to find a new job to pay the bills. With more and more people getting automated out of a job, UBI will become a necessity. We will need to increase taxes on corporations to fund it.
