What is wrong with politics

Okay I have just learned that congressmen, and senators are able to legally do insider training.  They have shown now that they are the best stock brokers.  That hedge fund analysts have nothing on them.  They say that they do not know what they are talking about, they would not have done something like that.  I cannot believe that they would have something legal for the government officials but illegal for us americans.  I just keep seeing what we are doing with government and am completely disappointed.
