Education

I'm not a fan of mobile phones in schools, but I doubt we can blame that for keeping students from learning math and science. Good teachers can make a tremendous difference in students' eagerness to learn the material. And hiring good teachers requires funding, pay, benefits, etc.

I'm 40 and many of my high school classmates wanted to become teachers as a career aspiration, and did. Not sure that's the case these days with book bans and loony parents in the US. Not sure if they have similar problems in other developed countries. Developing countries prioritize math, science, reading, computer skills, etc. And teaching is still viewed as an aspirational profession that kids want to get into.
