Lawrence,
Give em time.
They've only been around 3 or 4 decades.
Unlike the IRS who's been around off and on in one form or another for over 150 years, where the first tax rate was a measly 3% on, what was at that time, very high incomes.
Or take the monster EPA for example. Have you seen the size of the building they have in DC?
Or how about that humungous boondoggle Department of Education.
Governments do what governments do.
They get bigger and bigger until they suffocate the cash cow. Like a parasite on a host sucking its very life force until they kill it.
