It's quite easy to blame the common people, but I don't think it's that simple. The American Empire has been carefully constructed in a way that would not allow any real opposition to exist under any circumstances.

The Americans keep voting against their own interests. You may say it's because they're stupid or ignorant. While generally true, can you safely pin the blame on them? In a system that consistently undermines and sabotages the educational institutions, as well as gives the people little free time to educate themselves on their own - is it through their own fault that they're uneducated?

Furthermore, no matter which one of the two parties you vote for - you'll still be voting against your best interests. It's only a matter of choosing how much and in what specific ways you preffer to get taken advantage of and abused. All major news outlets are run by friends and families of the government, so they'll never host actual opposition, meaning it might as well not exist.

Americans constantly fight each other instead of working together to overthrow the authoritarian regime. Well, what else can they do? A silly post online may lead to termination of employment, which carries with itself serious risk of going homeless. Protesting may, and often is, answered with brute, sometimes lethal force. Can't work with a broken bone, so you get fired and go homeless. Or die from police brutality.

This is not a new, nor a simple issue. We're talking about systematic problems that have been festering over the last 200 years. There isn't one single party to blame, and it certainly isn't the average Americans - they are among the victims here.
