i.e. Your taxes go up $10,000, but you get a $10,000 payment. I haven't seen a cost calculation that explicitly factors this in. I imagine it's still expensive, but perhaps less than it seems?
It's a good article though. A lot of people vastly overestimate current social payment expenditures. They're much lower than I thought, and I am not in the camp that thinks basic income will be costless to implement by replacing social programs.
I guarantee that if/when this gets implemented, it won't be a wash for the middle class. The middle class is where the tax money is, and they'll be the ones bearing the brunt of the bill, as usual.
edit: more recent stats [0] show 104bn coming in, 5bn spent is social tax breaks, 0.5bn spent in food pensions.
