A profit layer that also prevented those other things from happening. These things can not be considered in isolation. People are more careful with their own money than the free money the government provides.

Will it have been worth all this damage to prevent the eeeeeeviiiiil profiters? It really already wasn't, and the accounting for the evil of our current policy is only going to get worse.
