We are not talking about imperialist sources trying to colonize a nation. Capitalism has its shortcomings, which can surely be discussed, but it isn't an evil plan to reallocate the most resources from a zero-sum game to the "foreign capitalists".
Of course not. We are talking about possibility to have businesses who will mostly employ local workers and mostly use local resources, some will maybe even pay fair local taxes, but whose majority of profits will move out of the country. Thus, wealth extraction.
This is not extraction. If they pay wages, this is profit sharing. At best you can argue that they should share more with locals.
Nope. Profit is what remains after wages and any other expenses, and is shared between owners or shareholders.
