I cannot figure out why the US writes laws in terms of nominal value while maintaining an inflationary currency. The majority of lawmakers agree that a law should be x with respect to the current value of USD, why don't they also agree it should be x+inflation for a future value of USD? Maybe with a circuit breaker for hyperinflation. They don't have to rely on third party inflation numbers, because the Fed is a government agency.
Do some lawmakers only support a law because it will have a lower (min. wage) or higher (tax) real monetary significance in the future?
