R8V9F5A2: Same here really.
Most, if not all, politicians in Sweden come from the upper-class.
To my knowledge its pretty much the same in most countries.
Well, to me it seems there are quite a lot formally uneducated people in the Finnish parliament, at least from some of the leftist parties, and the anti-immigration and anti-EU "True Finns" party.
There are some issues related to that though:
1. If you want to become a minister in the government, then for some of the positions certain formal education is usually expected. For instance, if you are to become a Minister of Justice, it is considered odd if you don't have a degree in law. I think earlier there was even a requirement for that, but at some point it was dropped so that non-lawyers could be positioned there too. Many consider this as a bad thing, and I kinda understand why.
Then again, our earlier finance minister of economic affairs was earlier a school teacher, probably no background in economics.
2. Even in Finland, campaigning for the parliament can be expensive. Where are you going to raise that kind of money if you are some unemployed no-name who just feels he/she has the right stuff and ideas to parliament? Rich people have easier to campaign and get (buy) coverage in media.
Of course being famous in one's party helps, or if you are very opinionated about things that people care about (e.g. Jussi Halla-aho who is mainly known for his anti-islam writings, or many people in the Green or leftist parties).
