DF is gaining because ordinary people are seeing their jobs being outsourced or underbid by eastern european citizens. In fact this is today the primary reason for why parties like DF gets more and more power. They are the only parties who actually takes peoples concern seriously. There is a much much bigger fraction of the western society who do not stand to benefit from technological progress, multicultural society and globalized workforce.

If anything what is happening right now is a national conservative trend where people who aren't benefitting will vote on the parties that are sceptic to progress.
