Private debt slavery! This is a terrible idea. Moreover, your cost of capital cannot possibly be lower than the interest rates paid by Western governments.
haha u have hit the nail on the head re: our bad pr problem..usually people go for indentured servitude rather than all the way to slavery though haha...
we think equity>debt for students because a) in bad times your debt is lower (% of income vs flat payment) and b) longer time scale allows transfer consumption from middle-age to years immediately after graduation
re: western government interest rates that's probably true, the uk has lost a lot of money on their loans which have very nice terms & conditions.. the US market still has a large private loans component which we think we can beat (for reasons above). to be honest though we are probably thinking more about the developing world (india, china etc.) where student loan financing isn't as available (particularly true at a graduate level)
finally, the x-factor is on the investor side where we can allow investors to bet on industries without having to be on a specific company because the income stream of someone working in a given industry is a better long-term proxy than a company in that industry (particularly if it's a new industry)..
