You said the USA is the only one with [Specific Type of Corruption] because other countries removed [Specific Type of Corruption]

I never said anything about other contries removing said corruption.

but you said cannot remove a [Specific Type of Corruption] in a country which is in a [System that Encompasses Every Country].

No, I said that you can’t remove corruption in a capitalist system.

You’re saying the thing that doesn’t exist elsewhere has to exist everywhere.

That’s a weird way of putting it, but yeah: Capitalism has to go, if you want to eradicate corruption. (Or a surviving biosphere, for that matter)
