That's because people are essentially the same the world over, regardless of their culture, religion, race, or what-have-you. A certain percentage of them are sociopaths.

There is a standard distribution of sociopaths across time and space. It's a function of Pareto's Law, better known as the 80-20 rule. 20% of the people do 80% of the work. Another 20% are responsible for 80% of the crime. 20% of the population always winds up with 80% of the wealth. And so forth, through all areas of human endeavor. This observation can be represented by a bell-shaped curve—a "standard distribution"—with a small minority at each extreme, but the large majority in the middle. The people who will take us to a police state are sociopaths—criminal personalities who don't respect the liberty or property of others. And sociopaths gravitate towards government, and eventually come to control it.
