I can still remember seeing a documentary about how American economists warned the US government at the time to not let American investers who were working for Middle Eastern oil oligarchs, buy up real estate on US ground and buy up companies.
But it happened anyway.
Than the Chinese came in and it happened exactly the same way, American investors working with Chinese corporations and Chinese investors to buy up US real estate and US companies.
Then there is the danger of wall street : Creating money out of thin air by overvaluing companies and corporations.
It happens all over the world. It is the free capitalist world process of gaining foothold in other countries, by buying up stuff and taking control.
The USA always advocated this principle but now the Trump government is not too happy about this.
Luckily, although it is the government of a country that creates trade agreements, we see that in the EU and for example the mercosur agreement with countries in South America.
This kind of holds a control over unbridled behavior from the capitalist market that might ruin an economy or destroy the environment by polluting.
Governments where there are too many lobbyists for big corporations are present, tend to be a bit corrupt.
Especially if oligarchs have too much influence over a government.
And we come full circle to the Trump administration again.
