In a democracy many folks think they are and will insist that the government "do something" to ensure that they have one.
In a constitutional republic, the government has no powers and thus no responsibilities, to ensure anyone much of anything, other than security from outside threats and very little else. They can "regulate" commerce, but the meaning of "regulate" is not to tie up in knots with rules, but rather to facilitate or make funciton properly, such as by overriding state level protectionist schemes. (such as the granting of tax preferances for businesses relocating from other states. Fortunatley what we have is a Constitutional Republic, not a democracy, unfortunatley we've been acting as if we had one for about 70 years now. Other than the mini rant about "democracy" I agree with most everything you wrote.
