More than half the country doesn't pay federal income taxes at all. How is that "so few?"
Look around you. Do you see an overwhelming crowd of people delighted to pay low tax?
That's depressing considering how much I pay in taxes each year.
Odd that you only mention federal income taxes, there are a bunch of other taxes that people pay (payroll, sales, excise and property to name some).
Only people who are paying taxes can benefit from lower taxes.
Or those who require zero government services. Your implication is that lowering taxes would have no impact on the services people receive. Does that seem right?
I don't think there are people who require zero government services. no matter what, you'll be benefitting from something -- at the very least, that no other army will invade
