What do you mean, 'does not mathematically work', Obama-Drama? Of course it 'works'. You tax everyone at 10% or 12% of their income and run the government bureaucracy and social programs with the income received from previous. If there isn't enough tax revenue to run the bloated, ginormous government at current size, then you start eliminating programs and zeroing out their budgets, starting with: Dept. of Education, 2/3 of the Dept. of Energy, Fannie/Freddie, the IRS, Farm Subsidies, 'global warming' funding, and etc etc etc.
