I believe that a strong centralized government was not possible at the time of the founding of this country due to limitations in communications and transportation. At the time, it made sense to delegate more power to the states
I lived through the civil rights era and saw the abuses of States rights. The belief that individual states can decide how their people should be treated. I have also seen the expansion in the US economically and as a world power since we moved to a centralized government
There are no major economic powers in the world that operates on a states rights form of government
RW, I trust the portion posted above answers your comment about civil rights. As for being the only economic power that operates on a states rights form of government, there's no reason we couldn't be (we're the only country that does a lot of things). The federal government has ALWAYS controlled international trade and tariffs, so that would be the same, bigger government or not. Likewise, the federal government has ALWAYS had the sole authority to conduct foreign policy, so that did not change, either. Big government has made us more despotic at home, and more aggressive abroad, but that would have likely occurred anyway. We got our present place in the world, (complete with a lot of the trappings of empire), largely by default, after two world wars innervated the former great powers of Europe, and not by having the federal government run roughshod over the sovereignty of the states.
Of course, you, as a government employee, benefit from Big Government, so it's understandable you don't wish to bite the hand that feeds you; however, those of us who are not feeding at the public teat may have a different take on the matter, which ought to be understandable to you.
