The USA as an economic and political system is dead man walking. It takes millions of dollars to get into US Congress or Senate, way out of reach of middle/poor class people, the majority. Almost all of your congressmen and women are either rich themselves or friends of the rich. Middle class is just another minority to them, a real nuisance.
You can email, write, fax and phone to your US congressmen every day for five years straight but his army of assistants will not most likely pass your message to him. Even if your message goes through, what he is gonna do about it? Probably nothing. After all, you are not one of his rich pals that provide him those crucial millions for reelection campaign.
