Some may argue, and with merit, that ours is inherently a conservative system of government, one that has prevented rapid progress on a host of important issues. Unlike a parliamentary system, in which the leader of the executive branch derives his or her support from the legislature, we often have divided government with different political parties controlling the presidency and Congress. This can often stymie big actions. Whether one thinks that is a good thing or not, it usually depends on whether those in power align with your political views.
