I used to read the Christian Science Monitor regularly. It was a good, relatively balanced, source of information. In the last few years, it has become a more-or-less mainstream piece of garbage. It regularly runs articles pushing the liberal agenda, without questioning or even analyzing the information presented. As another bullhorn for Progressive policy, CSM has simply joined an echo chamber. It may be a popular way to make a buck in the media industry, but it's not good journalism.
Which is why, when I read this piece, I began to question whether it's worth reading any more at all. The article implies the U.S. is somehow failing its children since, as a nation, we lag the rest of the developed world in providing pre-school education.
My parents divorced the year I entered kindergarten, aged 6. I had an older brother who was a year ahead of me, and 2 sisters who were younger. For the next 3 years, she was a single mother raising 4 kids and holding down a regular job. We all went to Catholic school. When my mother remarried, my youngest sister was just starting kindergarten. None of us had pre-school
Despite the lack of pre-school, we were all high performers in school and all of us got a college degree, while two of us continued into post-grad work. Maybe we were genetically predisposed to do well. I doubt pre-school would have helped, though we will never know for sure.
An early start to education is useful, but it is not necessary and does not guarantee performance. It's my guess higher performance later in life has to do more with factors such as the involvement and care of parents in their children's lives, as well as the relative success that allows many families to send their kids to pre-school. You can't replace a caring parent and loving family with a (hopefully) good teacher and assume that will yield great students. But that's the story you'll get from Bill de Blasio, Bernie Sanders, and Hillary Clinton (as well as a few Republicans). The OECD and CSM will push that agenda, too.
