Haha kiff, you really don't know the history about the Founding Fathers. You assume that all of the FF's were of the Democratic-Republican line of thinking. The Democratic-Republicans were essentially anti-federal government, pro state government, a strictly-formed Constitution and the like. The Federalists (led by Alexander Hamilton), on the other hand, believed in a strong federal government, and a flexible constitution. They also believed that the federal government could enact laws and impose them on the states if it was necessary and proper. Although people can argue that it is unconstitutional (mainly the Democratic-Republicans cried out about this) but it can help better the society as a whole, the specific law can be passed. Federalism, the CC, the Federal Bank/Reserve, even the Public option in the Health Care debate can all be saw as necessary and proper.
And about the Supreme Court. In the beginning, we had no clue what the Supreme Court would compose of, what it really was supposed to do, and what scope it would have, besides what was explicitly said in the Constitution. We knew more what the lesser courts would be made of. As time went on, it became more apparent that it would determine what is constitutional and unconstitutional. We wouldn't need a heavily influential Supreme Court if our constitution wasn't relatively flexible. It is because of it's flexibility, these constitutional vs. unconstitutional debates rage on, and there can be no "correct" answer to some problems.
Anyway, arguments that we are "supposed" to have a weak central, federal, etc government, or the powers of our federal government are "unconstitutional" today, are complete bunk. The Constitution wasn't written with exactly one school of thought, it was written with many schools of thought (Democratic-Republicans, Federalists, etc). It is interesting that back towards our conception, the atmosphere was way more partisan than today. It was actually encouraged by everybody to become extremely more radical than they were before. Also pretty much all the news back then had an extreme political spin, especially on pamphlets given out from political parties.
