So if the PM doesn't like the way the government is voting he can just force another election?  This seems like a very weird system of government.

The last time the Tories did it, they lost seats. It's not an instant win button, but it can help clear roadblocks. The UK's system isn't like the US's where the President's elected separately to party, the PM is just the leader of whichever party controls the House, so being able to shuffle that up is potentially beneficial.
That being said there is a worry that Boris at the helm will inexplicably get them votes from the people that just see him as amusing.

It's odd that the politicians simply don't scrap it.

They're the ones with hedge funds abroad that're poised to do better. They aren't doing this because they care about the people.

That's the norm in a lot of countries and it's not that weird. If even the government itself doesn't like how things are going and wants out, it's probably best not to force them to continue, for everyone's sake.

Ahh.  I see the problem.  All of your lawmakers are drunk.
