Yes, the US was involved in the coup in Iran, but again not as part of some plan to enrich the US. (They didn't want the Communists in control in Tehran and they didn't want Soviet warships and Soviet shipping in general to be able to operate from Iranian ports.)

Since the world is complicated and people are creative and opportunistic about how they try to make money, certain American individuals and certain small conspiracies of Americans probably tried to make money off of the US's interventions in other countries, but the US government as a whole basically never has -- at least not in the last 100 years.

While the US economy was dependent on oil from the Persian Gulf (approximately from 1957 to 2020) it used military force and pressure on governments to ensure American companies could buy Persian Gulf oil, but those American companies always paid the going price for the oil: Washington never tried to arrange so that any American interest got oil from overseas for free or for less than the fair price for the oil.

So I still haven't seen any example in this thread of Washington's extracting any wealth from the rest of the world other than through free trade, i.e., trade in which the non-American half of the trade entered into the trade voluntarily. (And again the US economy doesn't even need to engage in any free trade with the rest of the world for the US to be the richest country.)
