You go to school for 12 years, then possibly uni for 3-7, then are unlikely to receive more than a couple of months of formal training throughout the rest of your life, even if you change careers.

Virtually nobody does a university course after graduating. I don't think that's because university is useless (though there is room for improvement), or that skills are easy to obtain elsewhere, but a society that tries to load a lifetime of study onto people who don't even know what they are going to be when they grow up.
