My company invests billions of dollars of capital across the globe in institutional real estate and we will not touch Latin America with a ten foot pole. Now we take risks, i.e. investing in China, but if it was your fiduciary responsibility to guard this money would you trust Latin America and people like Hugo Chavez with billions of dollars?
I think from an eduadorian citizen's perspective, the question is not how much profit their oil can make for an investor in San Francisco. The question for them, is how to best manage their non-renewable resources in the public interest.
You said state ownership of natural resources, in and of itself, was detrimental to investment:
Cawacko: By the state stepping in and taking over privately run assets for example. How much confidence do you think that inspires in investors looking to place capital?
The fact is that the Norwegian government, through their state owned oil company, controls 60% of the nation's oil resources. (from previous link). In contrast, countries like Ecuador and Venezuela own about 40 to 50% of their nations oil resources, through their national oil companies.
So, norwegian oil is at least, if not more, controlled by the government than is Ecuadors or Venezuela's. Yet I've never, not once, heard bush voters and libertarians cry foul at the Norwegians. Why? Probably because we still sort of consider south american nations to be our pseudo colonies, who must do as we want.
The issue of investment in south america, is thus more related to the rule of law and political stability, moreso than the simple nature of public ownership of oil resources. No rightwinger is crying tears, or pissing their diapers, over the norwegian government control over norwegian oil.
