You don't just fire them, you reduce the pay to a point where you find someone competent at the lowest salary possible. Those who want to make more money than a non-profit like the government is willing to pay can go into the for-profit sector.

You write as though the federal government is an easily managed monolithic entity. Given the wide range of jobs in the DoD alone, it’s difficult enough to find out who’s competent (or not) and determine the lowest salary they’ll take. What you propose sounds simple, but it’s not.
Personally, I think it makes more sense to target unnecessary agencies and programs. If we stop subsidizing ethanol, for example, we could probably eliminate a bunch of ethanol program bureaucrats. That’s far easier than trying to reach down into the ethanol programs to figure out who are good employees (or not).
