Not really. Japanese kids are at least 100% better educated than American kids.
Some time back, there was an international scholastic testing conflab in Europe, they sent the best and brightest from NJ to represent the USA. Now the big joke in Belgium is how stupid Americans are.
Two of our children are stay-at-home mothers, The other two are gainfully employed, one in the U.S. Army as a combat solder (tagline), and the other works in the healthcare field, working towards becoming an RN. While non of my children will ever become famous, they are doing well.
I'd attribute that to your parenting skills, not the worthless, money-grubbing "education" system.
I’ve never understood why people attempt to compare the U.S. system of education, where every child is expected to attend formal schooling from age 6 to age 18, to school systems in other countries, where only those deemed capable of succeeding attend formal education. Apples vs oranges.
