I'd say the main reason for unemployment problems are growing populations (often through immigration) and increased automation. And government ministers mostly only being in it only for themselves (particularly if they're right wing, though I suspect most politicians are as bad as each other, here).

Jobs, niches can be legitimately necessary. But there are so many - the middlemen of the world - that only exist to give someone the bare minimum to do. Wealth creation, maybe, but raisons d'existence, hardly.

Maybe the way we educate our politicians (or at least select them) is the real problem? ;)
