Quality of public education in United States

The quality of public education in United States is much lower than that of Europe, in fact it is lower than many developing third world countries. US High School students are much less aware of the world history and politics, have lower mathematical and scientific skills, possess lower reasoning and judgement capabilities than European students of the same age. Universities are prohibitively expensive, the better the university, the more expensive it is. Students are often immersed on a lifelong burden of debt or get wiped out of all savings for an average college degree which costs a fraction in European countries or is free as in case of countries like Germany.
