How serious is the Dollar crisis, and do any candidates have what it takes to solve it?

It's pretty serious our government has been secretly pushing us into a global government with a one world currency. All 3 of the front runners will do nothing to stop this, Washington wants this to happen. Why do you think they put the pressure on lender's to give mortgages to ppl who clearly couldn't afford them. It's to drive the dollar down so the North American Union will look like the best option or only option we have left. Washington is stomping on the Constitution and they want to make sure we as Americans don't have any rights but rather are slaves to the government.
