It may be a 'low income tax area', with more regressive taxes used to fund the state and an equal or higher total? Texans need to pay for the same things, generally, as people in Massachusetts (though maybe they don't invest as much in schools, health care, etc.).
Is it the right thing to do? ehhh....
That said Texas isn't that low tax overall compared to a lot of other states. They have pretty oppressive property taxes.
