I'm fairly sure I'll still be paying taxes when I go out to eat with my family or go camping with friends. It's just not going to be as much as if I had spent that time working.
Most businesses fail anyway and knowing that even if you beat the odds and succeed, the reward might not be worth it because the government takes an ever large cut should give every reasonable person pause to reevaluate their life priorities.
As cliche as it sounds, money isn't everything.
I can't wait to read about all the entrepreneurs who come out and tell their story about how the tax rate at the highest level impacted their decision to create a startup. I'll be waiting forever.
