Foreign Aid v Free enterprise
This is a more complex problem than Romney states. The basic problem is that not all societies have the same degree of development as most western societies. In most cases, the ability of a culture to adapt to free enterprise is limited by its natural resources.
The question to provide foreign aid or to let private enterprise is still a case by case decision. The poorest countries tend to lack the ability to set pricing on their resources and have to depend on fair deals by the richer countries. Even a stable country can be knocked down by a natural disaster like earthquakes, drought and floods; events that can destroy the resources needed to recover from the aftermath of those events.
I see the free enterprise concept as an ideal that is rarely attained because of individuals wanting to maintain more control in such a way that it becomes impossible to enter the market to compete against them. There is also the bargain hunting that seeks to take advantage of weaker trading partners over keeping the trade fair for both parties.
I object to the social darwinism implied in letting the poor compete against the rich in a free enterprise. In other words, if the poor follow the richs' rules then they will lose.
