That's not corruption in the way that word is commonly used. Equating the deliberate misuse of public funds with non-ideal outcomes because of broader cultural attitudes towards government just destroys the meaning of the word.
And the extremely huge organizations that take the funds are not exactly misusing things themselves but they are facilitating the politicians.
It's been legal for congress members to inside trade, even. That doesn't make it acceptable. It's not just making decisions I "disagree with" that matter here.
