The liberal Marxo/fascist scream, “It's NOT FAIR!” So? ...What's the problem with the 50 State plan? If the Marxofascist want a highly progressive tax on the rich they can lobby their state governments for it.
In the end, the states with the most reasonable collection practices with thrive and business and people will move to their states. Those states with crappy collection methods will lose big time.
The left would hate the fifty state plan on its face because it would irrefutably prove what a failure their ideas are.
