> Germany (and many other european countries) has the idea of a trade school, in which one learns a trade.

And that is a problem. Want to be a plumber? 3 years education. Want to open a bakery? 3 years education. Want to work at a bank? 3 years education. Want to be a hairdresser? You guessed it right - 3 years education. Handwerker? No luck, 3 years education. Car mechanic? Forget it. It’s ridiculous.
