The people you hear giving up today have tried to fix the system. It's a little insulting to insinuate otherwise. When I was in high school, I tried to start a CS club, but no one was interested. I helped run MATHCOUNTS at the local middle school, and we had five people show up on a good day (<1% of the student body). Most students don't care anymore, and why should they when you have to fight the school to take AP Biology as a freshman? Gifted programs are being eliminated in the name of equity, and common core standards are lower than they ever have been. A friend who immigrated in seventh grade said America's seventh grade math classes are years behind China's (and she went to a better school than me). How do you get years behind in seven years?!
I don't think it is possible to fix the education system. The student body has adopted an anti-learning culture, administrators are lowering standards to raise their metrics, and most teachers would be wholly unfit for an ideal classroom, let alone the ones they're supposed to oversee nowadays. I am all for "burning the house down". I think the best solution would be to fire everyone, raise salaries by 10x, and then hire back 10% as many people. After all, the professorship pyramid scheme has lots of PhDs who might be interested in teaching for $300K/year.
