Some sites to always go back to see what plain understanding is.

Peter schiff has been outstanding when it comes to warning about the future and has been right about economy where others may have dismissed him. Its based on sound economic judgement. He is now trying to run for a seat in the senate but doesnot seem to be like getting there because of 0 experience in politics.
But what we can take from this man is the knowledge and a very critical look at the US government which also impacts the whole world as such so long as it is a super power.
Two sites
