Apparently I am paying less in income taxes than I would under a NST.
Again, it's not an NST, it's an NRST. There's an important difference. Maybe that's why you're confused.
BTW how much income tax, payroll tax, any gift or estate tax do you pay? Add those amounts to te 22% federal tax costs you pay in EVERY purchase - new or used. How much faster would your savings/investments grow if not for income taxes? Would you choose different investments not tax handicapped? or just let your investments grow faster? Would you be able to buy a larger home if interest rates fell to the tax free rate (a decline of say 25%)?
etc....
you're tied to the income tax b/c you don't pay any, huh?
