Have you considered that your market-rate could be 66% up (166*0.6=100) because everybody in your market has to pay 40% and wants to have a certain living standard? Or the other way round: how much will your income fall if taxes would be abolished?
If you want to see change, link up with other productive people. It takes one to get one. Those 40% are kind of a global standard. Instead of fighting big government, why not help to make it productive?
