For people making less than $250,000 a year cap the Federal Taxes to income earned during a 40 hour week,

Only tax income on a 40 hour week, any money made beyond that is yours and yours alone, reward, do not penalize, productivity.

Consider this;
Supposed you are unskilled single parent and making minimum wage, you make $7.50 an hour, so instead of taking the government dole, you opt for a 2nd Job (@ $7.50), now you are working 80 hours a week and paying the same taxes as someone who makes $15 an hour and works 40 Hours...

Is this right, is this fair, does this not fly in the face of the American dream?
