$200,000 a year net. Anything above and beyond that goes to the government for socialized health care, education, infrastructure repair, the space program, and right on down the line.
If my marginal rate above $200,000.00 annually is 100%, where is my desire to earn more than that $200,000.00 annually going to come from?
When JFK took office, the marginal rate was 75%--he and Congress agreed to lower it to 45%, with the ensuing boom in the economy. Your plan will make us all paupers.
The proper role of government is NOT to provide all things equally (i.e., we all are beholden for our 3 square and a cot) but to PROTECT all things equally. You and I each have the equal presence before the courts, the poll station. We do not have equal access to someone else's labor, treasure or life.
I believe that I have shown why socialism doesn't work while capitalism does work--because under socialism the workers don't realize a reward, while under capitalism the workers get rewarded.
