Around the world, many universities are subsidized by their respective governments, and thus can offer education for free or at very low costs to their students. Not all are attempting to be profitable, as they're quasi-government institutions. However, there are some fantastic opportunities to apply a price arbitrage overseas.
Take the Philippines as a great example. A smart businessperson could set up a university in the US, get the necessary accreditation and then set up a sister campus on the beaches of English speaking Cebu. They would have little trouble convincing students to move overseas for two years, offering a degree for less than $5k/year and effectively giving them a US degree with a " Philippines study abroad" option for half its length. They could hire teachers from around the world that would, put much of their content online and then graduate their students in the US. They would leverage the same cost arbitrage done by businesses in every other industry, have an international education experience to sell and find the best content to be delivered virtually. Content creation, grading, customer service, technology, and all the other "high cost" things done on the American campuses would be done by well-educated Filipinos at a fraction of the labor cost.
The Philippines is just one example. This can be done across the world and with more than one satellite campus. We just need the right businessperson willing to deal with the education politics of each region and the logistics. It will happen eventually.
