If the value of cash drops, and it may, that means the value of what cash can buy goes higher, includes houses, stocks, business investments, your dollar just does not go as far. Fixed investment accounts, the interest earned drops even lower maybe. The stagflation of the 70's caused houses to go up a lot, but we also had much higher interest rates then and also price inflation caused the value of dollars to depreciate, who knows what will happen. With the countries massive debt levels, it can not afford an inflationary spiral.
