PostEverything Democrats love universal pre-K — and don’t seem to care that it may not work

Kevin Huffman:

A Tennessee study found that students who attended the state’s pre-k program did worse by third grade than students who had been lotteried out. l

As campaign issues go, promoting preschool for poor kids is about as close to a no-brainer as it gets among progressives.

Indeed, when Hillary Clinton officially launched her campaign last summer with a call for expanded access to prekindergarten, the New York Times reported, “Of all the issues Mrs. Clinton could have delved into, early childhood education is perhaps the most obvious and among the safest.”

Both Clinton and Bernie Sanders have made universal, school-based pre-K a centerpiece of their platforms. Meanwhile, they’ve demonized any opposition. “They aren’t just missing the boat on early childhood education,” Clinton said, “they’re trying to sink it.” Sanders, not to be rhetorically outdone, claimed that “to turn our back on children at that period is disgraceful.”

And why shouldn’t we all fall in line on this issue? We know that children from low-income homes enter kindergarten already significantly behind their wealthier peers. Research shows that they hear about 30 million fewer words, they have significantly lower exposure to books, and their impulse control and self-regulation — often called executive function — tend to be less developed than in higher income children. So it makes absolute sense to look for meaningful interventions between birth and age 5.

Unfortunately, the predominant remedy advocated by those on the left is neither as effective, nor cost-effective, as people tend to think.
