Online Courses Subsidies
Heavily subsidize MOOCs, and efficiently raise the value of a country's human capital, and reduce unemployment.
MOOCs these days are often provided free of charge, and are a great way of learning new skills. However, there is no incentive to study them, so few people finish them (I've read the completion rate is a approx. 15%). Risk of spending time learning thoroughly something that will perhaps end up relatively useless, is a big gamble for most, when they could just take crap jobs instead of advancing their knowledge.
Subsidizing MOOCs, such that they would pay just like a regular job, would for one increase the talent pool of people highly advanced knowledge and skills, and reduce unemployment, because after all, such people are actually needed.
By heavily subsidizing MOOCs, any country could efficiently skyrocket its human capital and slash down the unemployment (after all, people studying MOOCs would suddenly be paid, and in demand after completing them).
