Therefore contrary to way you see it, criticism is a positive force rather than a negative force. Apathy will eventually lead to tyranny. There are always various forces at work within a large oraganization such as the US government. Some of those forces would lead us in a negative direction and others in a positive direction. People need to pay attention to what is happening.
Criticism is a healthy thing for a democracy.
Without criticism those in power are very likely to work against the interests of the people. Certain conditions in the US have allowed very competive enterprises to emerge which have dominated world markets. Food technology is very advanced in the US and so is agriculture. For example a box of Quaker Oats imported from the US tastes a lot better than a box of Quaker Oats produced in El Salavador. I know this from personal experience.
