Be glad most people can't do math, or we'd be even more screwed than we already are. The marginal impact of earning an additional dollar 'on the books' in many of these ranges is negative---VERY negative.
Increasingly I'm an aggressive proponent of junking out entire state, local, and federal welfare and social services sections and just cutting everyone---EVERYONE, no means testing---who is a citizen over 18 years of age and not in prison, a citizen's dividend on the order of $10k per year. You the people demand a fair amount of socialism, and while I think it's a bad idea overall, I think the citizen's dividend solution sucks the least. It at least would be highly transparent and, if directly linked to something nice and transparent (like replacing the income tax with a consumption tax or perhaps a national property tax, or, my preference, a substantial revenue tariff) would be very capable of defending itself as a political construct (as with the Alaskan citizen's dividend).
