The problem is that about half the jobs(maybe significantly more) that will survive automation are already fairly low paying jobs. We're talking teachers, chefs, most blue collar workers and nurses(or so I thought) etc.
If half the jobs are gone, then wouldn't that mean that taxes would have to
at least double in order for the system to not crash completely? If you're in a low paying(or even average paying) job, then why bother to work? Unless you're among the top 10% highest earners, you're not gonna be better off than the people on social care(or UBI in all likelihood), unless these people suddenly are way worse off than they are today.
Ultimately the top 1% would have to take the bill. This
should be a no-brainer, but seeing as human history essentially just is one long battle between the top 1% and the rest, I'm not convinced that they will. And if they do, they will probably go for a model that would leave the vast majority in poverty.
