This is, IMO, why UBI has to be timed almost perfectly for when the AI is ready to be the one who does the work.
That is what earned income tax, payroll taxes, and Medicare and Social Security taxes are.
If you believe this, then surely you also believe pension plans are the devil? If we can't have UBI then we can start by tearing away pension plans for all of the old people my tax money is being wasted on.
But yes National pensions can have the same problem, as is currently the case in France. The elderly vote themselves higher and benefits, waiting to back breaking taxes on the diminishing number of middle-aged workers
By the way, I support some level of rich-to-poor redistribution, not sure what's the optimal level but to get a reasonable range of where the optimum could be, look at the top 20 countries.
It is NOT about enabling "a modest life" or stopping people from working! On any serious UBI proposal everyone is still incentivized to work.
Once AI is able to replace all human work, that's a new situation. But this is not happening in the next 20+ years.
If you mean UBI that would allow anyone to stop working and live a modest life, that just doesn't work. UBI is essentially redistribution from those who work to those who don't work. That's not just a "safety net" because you could decide to stop working forever just because it's more comfortable than working.
I would possibly exploit such a system. Take 4% from my portfolio + UBI on top. Maybe work 3 days a week if I find a job that I enjoy.
