I completely agree that it should be easier to fire a federal employee, unlike you I've actually done that. However that is a world away and completely different from arbitrarily firing 10% of all federal employees, as you originally advocated. And arbitrarily increasing their workload and cutting their pay, which you also originally advocated. Good to hear that you now realize that's a bad idea. And that you'll stop using that $400 hammer example because it's ancient and was never true to start with.
We're talking real world problems with real people, "casual alternatives" are naive, unhelpful, and in the case of your suggestions likely to cause more harm than good. I spent years trying to save money in government contracts. It's super hard work that doesn't yield itself to simplistic "those government employees are all idiots" type answers. In most cases, the demands from people like you for "accountability" to avoid these phantom $400 hammers actually requires clauses that makes the contracts twice as expensive and costs the government hundreds of millions a year. You and people like you are in fact the problem, not the idiot lazy government bureaucrats you criticize.
I'm also a successful entrepreneur and have started and run two companies, so I understand the private sector and controlling costs. You're hopelessly naive if you think there is any correlation between running a government agency and running a private corporation. So again, until you have even the faintest clue on what you're talking about stop the rants and criticisms. Remember, "Better to remain silent and be thought a fool than to speak out and remove all doubt."
