If we are to use cash, and Americans still like it because it = freedom, then bills make sense. For larger sums they are much easier to use, easier to transport and store, and easier to count. Americans have loved the greenback since Civil War times, and there is no GOOD reason to give up the $1 bill.
The problem is the value of the dollar itself.
If the dollar were still defined as so much silver in a coin of a certain size, we would not be in the mess we are today. We wouldn’t have the debt we live under, you could save a dollar that actually earned interest, and baseball players wouldn’t be making $10 million a year. The policy of inflating the currency has ruined the country and created hordes of parasites that threaten to push everyone else out of the nest.
Having the dollar so defined (as silver) WOULDN’T mean we’d all carry around silver dollars…such coins would be found mostly in Vegas and Jersey, where they would have a use. But the $1 bill would be worth a dollar, and the mint would MAKE money producing halves, quarters, and the rest with actual value. A penny would again buy something.
There is a place for checks, for electronic transfers, for coins, and yes, for bills, but there should be no place for the counterfeiters now running the show at the Fed, Treasury, and our banks.
The new dollar coins have been largely rejected because the public recognizes them for the ugly, tinny trash that they are. They don’t store or represent much value, they are not easy to use, and they look like a cross between Monopoly and Bulgarian money. They ARE counterfeit slugs.
