Have your class envy always been this rabid?
The more you spend, the more tax you will pay under the FairTax, so that should make you very happy.
Right now, most of those hated 'billionaires and their useless heirs' aren't paying income taxes because they can afford to shelter their income from the tax man. When they spend their money on caviar and Rolls Royces, you will be getting back at them.
You should be on board with this plan just because of your hatred/envy/jealousy or what ever it is that drives you.
