Does corruption have an ideology?

I have been receiving more visits from the US lately, and I am afraid these visitors may have been misled by googling the combination of "public administration" and "corruption" (see Public administrations as corrupt welfare systems). This is of course not what I meant to say: I strongly believe in society offering a series of services all of society is supposed to benefit from, such as education, health care, a prison system, garbage trucks and fire brigades. Recent ideology is that private enterprise will organize these activities more efficiently. Two decades down the line, it is time to evaluate whether this dogma is actually true, and if so, why.

The other big question is: how do we make sure that these services are really managed around the social benefits that justify their existence, and not for other, e.g. personal benefits. The Soviet system was unable to solve this question. So is ours.
