> The trick is to have a two party system and agree on all the important points.
This is the exact characteristic about US politics that Americans wish were removed so their government was better for them. It favors a two party system, so no one is actually represented and have to choose between two parties they likely only agree with on few points, unless they are subscribed to that party's propogandic kool-aid.
The UK has the same system with the same problems.
It always converges to a two-party system eventually, the US just speedran the process.
