The effective total rate of taxes may not be 55%, but the rate on income earned would be. Who would work full-time in an ordinary job if it was taxed at 55% when they simultaneously get paid a generous UBI?

Also remember you counted in pensions into your budget, those are separate from taxes. So the net profit from working would be maybe 30% or less - ridiculous!

Ok that's fair; I completely ignored the ~$36,000 deduction I'd be getting.
