You have missed the point of the article. The complained about activity is not writing a contract to provide a product or service, which is clearly lawful, but rather hiring contractors as individuals to augment the bureaucratic staff, which is a felony under the Anti-Deficiency Act.
As an example, Trump complained about EPA processes taking twelve years without approving a highway. That isn't done by federal staff. That takes an army of illegal support service contractors.
This has been illegal for over 100 years and remains illegal today. The reason is that there is no cap on the number of bureaucrats you can have except employment caps set in law. But these illegal contracts are used to evade these laws. You are not winning from this. The swamp is. The money all stays here in D.C. hiring folks from funds that should have gone out to the states.
That money should never have shown up in DC in the first place, much less returning to the states.
At least these contract workers don’t get a federal pension or benefits. And they can be fired at will.
