I think that it was, and intentionally too. The founding fathers and the framers of the constitution were terribly concerned about the possibility that the new American government might eventually become just as autocratic and oppressive as the government that they had so recently rebelled against. So the framers were very careful to create a separation of powers between the executive, legislative and judicial branches. They wanted each of the branches to serve as a speed-bump to prevent any of the other branches from collecting all power into its own hands.
Which isn't necessarily a bad thing. There's this idea circulating that the best government is the most active government, and that government effectiveness is measured by how many new laws are enacted each term. But are more and more laws, micromanaging every tiny aspect of human life, really the goal that we should be pursuing?
