There are also limits: MPs individually vote, and on something that was hugely controversial they would defy the whips. It's not "the Government" but a collection of individuals. And in the end we can vote them out and overturn absolutely any legislation in the next Parliament.
Government deadlocks are not always a bad thing, either, particularly when the issue is controversial. I'd argue that it is far better to have an issue debated and for compromises to occur, than to have one party's solution shoved quickly into place. This includes so-called emergencies, which are often excuses to go after civil liberties.
As a UK citizen I agree with you, the real problem is the apathetic electorate though, we get the politicians we deserve.
Germany has the same problem caused by PR Andrea Merkal needs 1 green vote to stay in power so buy buy Nuclear power
I am sure Rep or Dem whips visiting the HOC must be jelous of the power that their counterparts have.
