Counterpoint, wouldn't it be better to have 3 weeks for Christmas, 2 weeks for spring break/easter, 2 weeks in the summer and then an extra week or two break in the fall? Depending how you organize it kids could have up to 2 weeks off after every quarter/major exams.

Or, going the other direction, you could condense it down to every other or even every Friday off, meaning 3 days weekends and 4 day work weeks for youth.

I get the sentiment, that having 2 months or more off as a kid was great and I certainly enjoyed it at the time, but looking back it was such a bad system and I certainly would have adapted better to school if I had more breaks from it throughout the year rather than one long absence in the summer. It's not that summer vacation needs go away entirely, it just needs to be revamped to a more manageable break and that excess time off spread out throughout the year, particularly around times where students experience the most stress so they can decompress.
