Idk about the US, but the 'government' fraud that I know of, does not show up in the tax office records or in the foreign aid accounts. The common thing is that civil servants/officials are bribed. At usually on the cheap too, so it'll take a lot of digging to find it, and worse, prove it. But, this kind of corruption is probably even more widespread among companies. If you want to exact justice, that's the place to look.

One of Trump's executive orders has shut down enforcement of the Foreign Corrupt Practices Act. This government is absolutely not trying to root out corruption.

In private companies people probably consider the issue to be 'less wrong'.

It's up to the owners and their management how they run it, right? So it's more about discrimination than government-style corruption.

While no doubt that brazen bribery occurs at all levels and in a large range of dollar amounts, I do not think this is such a serious problem that it requires the nuclear option he is employing. There is a bribery-adjacent phenomenon that is far worse. I don't know what to call it. Favor-trading? But there is no quid pro quo sufficient to prosecute in most cases, and any attempt to do so would look like (and probably actually become) a witch hunt.

If a civil servant is just being extra cozy to some private entity knowing (but without anything that would amount to evidence) that they'll be able to sail into some nice lobbyist gig in 3 years, where is the bribe? It was never promised. It's not guaranteed (circumstances could well change before that becomes possible). How much is that shit costing us? And while I'm sure that some would call that bribery too, it's juvenile to do so and counter-productive.
