A system where corporations take on government responsibilities in return for monopoly powers and other market barriers is something like the worst of all possible worlds.
It is a bad system, for sure, but the problem is that the stock markets reward corporations time and time again for entrenching themselves into monopolistic positions within their respective economic sectors.
Regulatory capture sucks, but good luck telling a congressman that they can't accept ~bribes~ donations or promises of cushy future employment situations (or jobs for their relatives) in exchange for favorable legislation. Those who are uniquely positioned to end the problem are also uniquely positioned to reap tremendous rewards from ignoring the problem.
