The government push to reopen schools is explicitly related to getting adults back to work.
Also the schools staying open for key workers so they could work is a clue.
Yes the priority is education. But. There is the point about why it came into being in the form it is. Here's an article:

The point of education is not raised really, it's taken for granted. Which is fine, I think being educated is very important. No question there. It's still accepted though, again unquestioned, that the main reason is to be able to engage in work in the modern workplace, and hopefully get a decent job. It's about the economy, about capitalism.
This has been really shown up in the fees at university thing. You need to spend money to make money. The idea of knowledge for the sake of knowledge, interest, love of a subject has all but gone. I find this really sad. It's all about money.
If this becomes longer term what happens to the philosophers, the artists, the creatives. The artists etc etc. Will these things again become the remit of the wealthy?
Anyway I'm getting on a rant...
The origins of universal education, the uniforms, the rules around suppressing individuality (hair etc) all speak to a certain aim as well.
It's all very interesting.
I can understand why people say it's not childcare. But childcare is an important by- product and the reason it started was to produce a population that are work ready. Uniforms, timekeeping, taking instruction from others etc. The fact it enables (mainly) women to work more is a benefit to the economy that came later (and it's still an issue for women).
