Associate's is a two year degree people get from junior or community colleges. Many types of nurses have associates degrees and great jobs that pay well (albeit they can go higher and get paid more.) The top 30 or so jobs that require an associates pay a median salary of $50,000. Since people with associate's don't have a lot of loan debt, if any, they tend to have higher standards of living than people with bachelors or even higher. In most of the U.S $50,000 gives you a very comfortable standards of living, especially if your spouse makes just as much.

Furthermore, I know many people without degrees who are well educated voters. This includes a close friend of mine who is a painting contractor who makes $30,000/yr. Having started his own business, and been successful for 30 years, I think he deserves and has earned a right to vote on how other people affect his wellbeing and his business. Europeans have historically tried to eliminate social classes as well as economic classes, but from what I hear on the internet you guys are still behind Americans in the social class sphere of things. Plumbers, physicists, businessmen, medics, doctors, cashiers, and lawyers are quite frequently best friends, despite having huge income disparities in the U.S. Nobody is looked down upon for not pursuing formal educations. Trades aren't looked down upon as for the peasantry. And people who don't have degrees aren't viewed as less human and deserving of rights than others. Despite your pride in your welfare schemes and forced equality, it makes sense in your societies of stratified elites that you need such things. One can blame feudalism and its lasting effects, I guess.

My father only had that and he ended up making over 100k a year as a supervisor in a power plant. So not entirely useless. He could have went back to college at one point to study mechanical engineering (his work would have paid for some of it), but he declined because it didn't make sense financially at the time.

Then the better option would be not to force people to vote. Let those that really know what they are voting for and that care go vote. That's how it's worked here until Obama when everyone went out and voted. Saying someone can't vote because they're not educated enough is wrong. A degree doesn't in anyway make a person smarter than another that lacks the papper saying so. 

Yet you believe that people without degrees are less than people with degrees and should not vote. Quite socially egalitarian there.

Tell that to people in the nursing and IT fields.
