According to this article, summer vacation makes children dumber and fatter. The article even goes on to say that it’s the poor and racial minorities who are hit the hardest.
But don’t worry. There’s a proposal to have the federal government get involved to solve this problem. Supporters of the program claim that it would cost less than $2,000 per child per summer. Of course supporters of these kinds of government programs always understate the cost, so I can easily see such a program costing far more than that amount.
