I just saw a headline on Time magazine bringing up, once more, the old topic of getting rid of summer vacation. I presume they want to replace it with the system in which the same amount of vacation time will be spread around the rest of the year, easing up pressure on both students and teachers for the rest of the school year.
The headline's sub-headline also mentioned that this was being brought up again because summer vacation makes kids fall behind, by forgetting what they learned over the summer. And yes, I see their point; it was indeed hard to try remembering the bullshit, meaningless liespropaganda facts drilled into kids' heads by "teachers" in an educational system that has not changed significantly since the late 1800s. So yes, if they were unwilling to change a system that was a piece of shit to begin with, getting rid of summer vacation would be a logical decision.
However, there is a huge problem with this plan. The problem is that schools don't have much in the way of a maintenance budget; that tends to be one of the things that gets slashed first. And summers get HOT. If I had kids, I would NOT want them to be in school during the summer, without good, working air conditioning.
