Iran and untapped markets
I think I've figured something out here. The population of Iran is 88 million or so. That's a lot of people. Basically every western/civilized country on earth has completely saturated the debt market. Everyone I know is absolutely paycheck to paycheck. Nobody can keep taking on debt. In order to expand the debt marketplace, you need new bodies. This can be in the form of countries that haven't had western influence/companies, OR by importing shitloads of "migrants." Thru both methods you create new debt markets.
Maybe other anons have some insight here.
