So someone in Oklahoma should pay more federal taxes that someone in California ... why? California sets its own policies, whether its housing or the social services they provide, as does Oklahoma. Someone from OK does not benefit from CA policies that provide more social services, so why should they subsidize them?

> do we support double taxation or not?

I'm taxed on my income and I'm taxed again on sales tax and if i transfer above a certain amount I'm taxed again as a transfer or gift tax, and if I leave an estate I'm taxed again, and if I use it to buy a home, I'm taxed again...

If you're actually against double taxation, you should be against all of these taxes because you're being taxed on top of already taxed income.
