But quite a bit of that was paid for through personal income tax. So you're not saving anything there... it will be money you no longer have to pay for universal income with.
When you do the numbers, no matter what you cut, there's not enough to go around. You either make it not universal (in which case what little political support there is evaporates) or you make it so low that it's not enough for someone to live in a cardboard box eating Chinese-melamine-poisoned dogfood.
The math doesn't work. Your taxbase is eroding at a faster rate than your employment.
