I grew up in Florida in the late 80's/early 90's and now have 2 children under the age of 7. Their days are almost exactly as you describe your children's days (and in public school). I think you need to take anything coming from US news with a healthy dose of skepticism. I do think it's healthy to discuss these topics to help remind us of its importance, but it's not as bad as everyone would have you believe in the online world.
