Part of the problem is that a subset of the right wing wants privatization. In order to encourage privatization, you actually want the public sector to be as bad as possible so there's greater outcry for subsidized privately-run alternatives.
A fair-sized proportion of the right wing (loosely defined to include libertarians also) favors privatization. It is fair to say that some of them want to believe that the public sector is as bad as possible. It is unlikely that any are deliberately making it worse.
