Hear me out!
The national government announces that the US will no longer be minting pennies. And that from now on every tax will be ROUNDED UP to the nearest nickel. At the same time every check the government sends out and every expenditure will be ROUNDED DOWN to the nearest nickel. .
All the extra revenue gained from rounding up would be applied to reduce the national debt. And the rounding down would add up to some serious savings overall. It helps on both sides of the financial ledger.
Think the plot to Superman III or Office Space but on steroids and on a much larger scale.
How would this not work? People wouldn't even notice.
