Let's Make Money explores financial exploitation in both emerging and developed economies by following the hypothetical and hidden trail of an ordinary bank account depositor's money. The film illustrates that while globalization is reducing the cost of goods and services, protectionist subsidization in developed countries reduces workers in the developing world to virtually unpaid slaves in an effort to compete.
Privatization and real-estate speculation in the developed world are also touched on briefly but I think the filmmakers could have expanded greatly on the clear ramifications of this rather than focusing mostly on the nationalistic sentiment against foreign investment.
My favourite part of this film is John Perkins' interview. What John has to say is the key to understanding how and why the United States goes to war with countries that pose no obvious threat while propping up some of the most vile regimes on the planet at the same time.
