I (and I'm sure others) would obviously agree. just a smattering of the obvious cases

* for years people have noticed that many members of congress use privileged information to pick stocks.

* lobbying post-Citizen's United has a very decidedly "buying politicians" aspect to it

* a congressman (Menendez) was literally arrested while holding gold bars from a foreign government. he went to prison, but is the only person on this list who has iirc.

* the former mayor of new york (a long-time police offer) was embroiled in a Very Funny, very obviously true corruption scandal for turkish airline tickets. the prosecution against him was dropped for no good reason.

I think there's probably plenty of minor corruption around. A lot of it takes the form of "I have control over funds and I am going to award contracts to people I'm close to"

Or maybe soft bribery, like government officials being wined and dined by lobbyists. I'm sure that isn't "supposed" to happen, but I'm also pretty sure it happens a lot.

This sort of corruption exists a ton at corporations for sure, so I am hard pressed to think it doesn't happen in government
