I assume you feel the suppression of political opponents is a major issue because it causes a government to become corrupt, abusive, and make bad decisions without the accountability that comes from criticism and competition. I agree.

But Singapore has made good decisions and hasn't been abusive or corrupt. (No government is without sin or without mistakes, so I mean Singapore isn't abusive or corrupt compared to the US and Europe.) Their economy has boomed, their standard of living has risen dramatically in a short period of time. Aren't you curious about how they did it?

Political systems have evolved and improved throughout history and will continue to do so. Western democracy is not the best government that will ever exist on Earth.
