Cut the Value of anything with a $ in front of it in half, to increase the value of the US Dollar.

Inflation continually decreases the value of any currency over time. Deflation never happens. As a result money gets more and more worthless, so more is printed up, eventually resulting in more inflation (It never stops). But, if the entire country which uses that currency, were to in some way mandate that everything related to or using that currency, simply cut the monetary value of everything in half. It stops looking so inflated. Everything would include any sort of Fee or Tax, Wage or Salary, and any kind of Cost or Expense under the sun that uses that currency (Everything that has Anything to do with the US Dollar).
Make the Penny Matter. The Electric Horse at the grocery store needs to pay itself off again.
