I can’t tell you why in Europe, but I can tell you why in Belgium.
In Belgium, voting is mandatory. Everyone over the age of 18 gets a voting summons, needs to take it to the voting office, hand it in, and vote. If you don’t, you get fined.
Since WWII, and up until the last elections in Belgium (1999), the two main parties in Belgium had been in government, the rest always in opposition. The two parties I’m talking about were Christen Democrats and the Socialist Party (loosely tranlated as Labour, I’d say).
It seemed to work fine for quite some time, this coalition, until they got complacent. See, they were always voted back in office, and after 50 years, you start thinking you’re invincible.
In the early 90’s, both parties got riddled with scandals (I have to give credit to the excellent investigative reporters we have at home), and people started to see something was rotten at the core. Even more scandals broke out, and the icing on the cake was 1996, the whole Dutroux thing.
Now the Vlaams Blok had already some supporters, notably among the lower classes (the lower the education, the more radical the vote, studies have shown), but when the public started to lose faith in the honesty and sincerity of ther two main parties, they punished them by giving their vote to other parties.
Belgium is probably a very complicated case, as there’re two different “entities” in one nation: the Walloons, who are mainly socialist in inclination, and freethinkers, the Flemish, who are mainly Catholic and conservative. that’s why there’s a far right party as Het Vlaams Blok in Flanders, but not in Wallonië.
It took the Belgians a reasonably long time since the birth of the nation (21/07/1830) to reach some financial security, and the richer you are, the greedier you become. The first immigrants in Belgium, were the Italians. The Belgian government shipped them over in droves to go to work in the mines (late 60’s, early 70’s), as the Belgians did not want to work there, themselves. After that, there was an influx from the Belgian ex-colony, Zaïre, or Congo, as it’s now called.
And even later, as any Welvaartstaat (Prosperous State, or “First World Country”) can expect, there were immigrants from states that weren’t doing so well, economically speaking (Turkish and Moroccan people are the two biggest minority groups in Belgium).
The way Het Vlaams Blok gained power, is through the same strategy Hitler employed in the 30’s, namely scapegoating the immigrant populations for everything that was going wrong.
The working population was unhappy, they saw their money being squandered by a corrupt government (and if you want anyone to get moving, touch them where it hurts: their money), and they did not seem to be able to get through to these parties. (VB just blamed the immigrants for all this. They shouted that unemployment would drop drastically, if all immigrants that had settled here since the 70’s, were to be deported back home.)
So, when the next elections came, and because voting is mandatory, everybody queued up to vote in protest, meaning they gave their vote to smaller parties, and not to the two main parties they’d been voting for for 50 years.
Since Guy Verhofstadt is Prime Minister, (he’s a Liberal), there’s a “rainbow” coalition in place in Belgium, and it seems to work fine. VB is actually losing support, now. The government is listening to the public, and they’re actually doing what they were elected to do in the first place: represent us.
Not abuse the power they have and use it only to remain in power, which is what I see a lot of governments doing (like the Irish one, for example. But I agree with the old adagio, in a democracy, people always get the government they deserve. Irish people suffer from a political apathy. They don’t care. They’ve never seen it done right, so they don’t truyst any of theiur politicians. Sad…not just for the politicians, but for the population, who refuse to participate in politics, can’t be bothered to vote, and thus leave the way open for a corrupt government to do as they please, and get away with it, too.)
