Your numbers might actually mean something if the qualifications required to enter ever stayed the same.
Just one example. We all know all WW2 and Viet Nam vets were required to have a high school diploma to serve.
Education standards have increased. But we are also seeing increased obesity. And less physically fit kids.
Again, it is not the kids fault. We have become a wealthy nation who has been into slow decline for about 100 years.
