Memo to Congress
You've tried twice. And failed. Most sensible people* would take this as a sign that you have to change your tactics in order to succeed. If you really want people to accept a dollar coin, you need to provide a damn good reason**. Like, STOP PRINTING DOLLAR BILLS.
I mean seriously? This argument that people don't use the coins because they don't like them? Is bullshit. If you stop giving them the option of paper dollars, they're not going to refuse to accept the coins, because otherwise they don't get their money. And they won't not spend the coins once they have them, because they're not going to waste the money either. I mean, what am I missing here?
*I know. This is the U.S. Congress we're talking about. But I'm trying to be optimistic.
**And no, I don't think "seignorage" will work in this situation, because it seems like it would require the coins to be in circulation in the first place, which wouldn't happen unless people actually start using them as money.
