Yes it fucking sucks. But please point out to me any other democratic country that is not a 2 party system? I don't know of any and maybe that says something about democracy itself. This may be any issue that can't be fixed.
This is not a failure of democracy. It's a failure to teach people about voting systems and game theory.
Proportional representation is the solution to this, so that new ideas can enter government incrementally instead of only when they get the majority vote, by which time it's probably too late.
But this is really hard to get through people's heads, because it is very hard to get someone to understand something, when their influence and power depends on not understanding it.
In the past decade, we've had parliaments only able to establish a majority by negotiating a deal with a third party or independents.
