That's the cost over 4 years. Most people will be able to get financial assistance to help pay for that and you easily manage to make 30k (or less with grants) in 4 years to pay for school. People making below 35k per year are going to pay practically zero taxes. You can work about 15 hours a week making $10 per or full time over the summer to pay for that.
There's no need to take on any debt.
People in the US make considerably more money than those in the EU and, generally pay less taxes so there's a lot more disposable income available. I think people here prefer to be able to just get what they can pay for rather than hope the government will let them pursue the education they want (there are aptitude tests and quotas in some EU countries).
It's not really better ir worse, it's just different.
