They can't; government here is mere servants of society. We've seen socialists dropping welfare when it was needed, now this libertarian government raised VAT. No matter what ideas drive the party, they actually listen to analytical people doing their math. And of course they'll be replaced in a few years by some kind of reds (maybe with greens, maybe with something else), similarly powerless, as any government should be.

The only strong power in our politics is Swedish language party that always has 5-10%, any coalition, and just one line on agenda - swedish language. Awesome mockery of serious politics IMO (and at the same time more serious politics than most).
