Children today are retarded - physically, mentally, and emotionally, and they come from retarded parents.
The situation is going to get worse, not better, despite how many PSAs or "First Five" programs you trot out.
It takes a village to raise a child, but parents don't trust the village so they try to do it all themselves.
Then they realize it's too much fucking work for 2 people, 2 people who both need to keep their jobs, 1 person (since single parents are more common than not), or 1 person who's working a full-time job (or two). So the kids get plopped in front of the TV, a tablet, etc. and vegetate. Outside is dangerous, so kids don't play, they Google Play and get fat. When they enter school, the state becomes the sitter. Education and social interaction are to be avoided - the goals here are to not get sued and to try and make money off of attendance records and performance on standardized tests.
There are only 3 simple steps to solving this:
1: Stop having kids you when you can't handle kids (financially, mentally, temporally).
2: Stop having kids with people when you aren't both committed.
3: Stop wasting time coddling the broken kids in school - leave them behind in the bad schools and dumb classes and let decent kids get an education based on learning, not on administration.
Of course, none of this will happen because it involves people taking responsibility for themselves and their kids.
