I'm not taking your claims at face value without a solid citation. But in any case, they would seem to underscore my point that just throwing money at a problem isn't sufficient. The money has to be spent in the right way, and it's not obvious how to do that in advance.

And rent-seekers are omnipresent. Greed motivates workers in the public sector just like it motivates workers in the private sector. There's nothing about the phrase "you are now working for the government" which makes someone magically less greedy. That's another point that your account underscores (assuming your account is accurate).
