They already have daycare picking the kids up. Now they have to drop the kids off, and the kids can't really do anything at daycare because they are quickly getting into the bus to get to school, then when off school there is less time to do anything before their parents pick them up again.

No high school student is going to daycare though, and this law is specifically for high school students.

High school has sports and activities though. I know many families that use the sports team as if it were a day care. If they do sports the kids usually get out somewhere between 4:30 and 5:30. Where I live now, a lot of the high schoolers are in school 7:30-5:30. It’s pretty ridiculous, since they also have homework. Many high schools seem to be in the process of transforming themselves into juvenile prisons designed to keep teenagers away from the rest of society.

It must be a fairly low portion of high school students who do after-school activities every single day, right?

Sports can happen before school

It’s not an analogy. One of school’s main purposes along with sorting and ranking and reducing their tendency to creativity and independent thought is day care.

and getting them to sitdown, shut up and follow instructions without questioning the boss.

This is a bit anti-DEI. Special needs and kids with behavioral issues do need that. Now they would need it twice a day.

Not with after school activities like sports or clubs.

The bigger issue is requiring some sort of pre-care. Which if necessary, makes this whole law moot because you're waking the kid up for that.

not really, it doubles it. Instead of having to arrange for care/transportation/etc once for a few hours in the afternoon, now you have to arrange for it twice for an hour or two in the morning and an hour or two in the afternoon.
