You just said it yourself though. You live in a country where the entire population would fit in one metropolitan area of the US. What would work for your country wouldn't necessarily work for ours because we have people living in dramatically different conditions spread across thousands of miles and over 300 million more people to deal with.

We have a state with 100,000 square miles and only 600,000 residents. We have another state that has a little more space but has 40 million residents. Their circumstances are so vastly different that the policies of one would be very unlikely to work well for the other.

> LOOK at the results of America's screwed up voting system! A deranged madman in power, the economy in collapse with no rescue even planned, and a virus growing exponentially with no plan to fight it.

America uses first past the post. It isn't great, there are many better systems later developed. If we were to improve our voting and party system it would benefit the entire country massively.
