Public Institutions

Who would better serve the public? Private corporations, or Public corporations (and i dont mean in terms of it shares being publicly exchanged).

Furthermore, what is the difference between the two?
Further furthermore, is there anything that one can do that the other cannot?

Bonus points if you answer the question without using the word capitalism or communism :evilfun:

private corporations, when presented with an opportunity to make money and not help the people so much, will always go for the money. MTV, nuff said.

the only thing you have to look at is what motivates the two. if the public org is out to make money for themselves, then they suck. private corps, as a rule, are out to make money for themselves and therefore suck ass.

one has potential, one does not. sure, sometimes the way for private orgs to make money is to help, but thats only a coincidence. when the public orgs help, thats because they actually tried to do what they were intended to do.
