A bunch of studies came out saying that students are better with more sleep and generally waking up after 7 is best so we get this law. The problem here is that I am betting that the kids still get home before their parents from work and now they will have to start after their parents leave for work so it will put an economic crunch on dual working parents.

Why don't kids just go to sleep earlier?

Isn't part of raising children teaching them self-discipline? Things like putting down the electronic gadgets at night, not consuming stimulating food/drinks in the evening, etc.

It's shit like this that makes California look so ridiculous to the rest of the nation.

No, it's biology.
