These anecdotes and surveys and scores keep coming up every couple of months or so, our kids are dumb as a box of rocks, the education system is broken, and then the news cycle moves on. The issue didn't develop overnight, it's not getting fixed overnight, but public schools, colleges, local school boards, many parents and many teachers aren't doing anything to fix the problems. All those parts need to come together before we can get out of this very deep hole the US is in with regards to education.
Also have to struggle with the string pullers who prefer an ignorant, easily distracted populace to play their chess games with.
