Do the flat-tax math and it falls apart. If the poor and middle class paid their "fair share" under a flat tax, their taxes would rise dramatically. The wealthy, who pay the lion's share already, would fare better on the backs of the vast majority. Unless we take a notion to repeal the 16th Amendment, a progressive income tax remains the best way to maintain social harmony. Put into climbing terms, try thinking of it as a mountain that gets progressively steeper as you approach the top. The only reason guys like me are considered right-wing is that we don't see any value in punishing wealth and those who produce it. The lefties you find here don't think anyone should be allowed to reach the aforementioned summit.
As for your gold standard nonsense, you may want to put this very-fringe notion aside for good. Take a look also the idiots who promoted free silver in the late 19th and early twentieth centuries, or, antithetically, at Nixon's unilateral unpegging of the US Dollar from international gold in the 70's. This economy is based on one thing: faith in the federal government's ability to make good on its monetary commitments. That faith is in jeopardy because of unchecked, politically-motivated spending on both sides of the aisle.
