If California taxes people and businesses at insane levels, maybe we shouldn't replicate insane level of taxation everywhere else in U.S., on the off chance that it is not, in fact, an optimal level for generating wealth for the people.
Maybe Texas and Florida should be allowed to enact competing taxation schemes so that we can see which one is better.
And maybe Americans should have a freedom of movement within U.S. without having their private property confiscated by the state when they try to leave.
The justification for taxation based on residency is that you use commons like roads and school and police that the government funds so you need to contribute to funding those things.
What exactly is justifications for hitting people with more taxes when they try to leave the state?
