Some form of guaranteed-annual-income would be less disruptive than raising minimum wages to $15.00/hr.
For instance, if every adult were given the equivalent of (say) $8.00/hr (taxable) and allowed to earn more without claw-backs (except for normal taxes); then a $7.00/hr job would provide an income equivalent to a $15.00/hr job.
Incomes would be more “equalized” (the objective leftists would have us believe raising the minimum wage would achieve); there would be no disincentive to working (unlike the current welfare system, anywhere in 1st-world countries); and current wage scales would not be destroyed.
Raising minimum wages only guarantees more work for robots. A guaranteed minimum income would enable humans to compete with robots (for a while longer, at least).
Done right, a guaranteed minimum income would reduce, not increase total welfare program spending.
Eh?
There is no such thing as a guaranteed income that can be “done right”. The right thing to do is to eschew socialism and all of its micromanaging regulations, so business and agriculture (the latter especially being the source of self-employment) can be free to flourish.
