Just watch what happens in Haiti,
see how long the US occupies Haiti,
and see what US and other countries go in to "help" the Haitians by limiting their capacity for self-support so they are forced to "buy rather than make", eg, their own food.
This happens anywhere corporations move in to poor countries. eg, Monsanto selling patented, sterile seeds that are Monsanto-insecticide-ready so the farmers have to buy their seeds from Monsanto every year, as has happened in Africa and India.
The US invasion of Haiti for "humanitarian" objectives is really an opportunity for a predatory corporate invasion.
