The American government will not collapse, it is just going through a hiccup phase as it does every couple of terms with people in office. Our government was built on instability, sneakiness, and a will to change ways to better the people, so it is expected that every couple of terms things will go south and eventually the government will grow strong again.
In fact, it's going to keep growing and growing while picking up more and more power along the way. Americans are going to lose any say or freedom. This is the age of the death of freedom in America. We have become a 'police state.' The government is naming Americans terrorists for speaking up. Americans are under attack, from it's own government.
