People have to wake up like 6-7am or earlier just to get to work. Then they are so tired they're lot likely even very productive until after lunch.
Would life and business be way better if everything started at say 11am? Everyone could sleep in a bit, have some time to chill in the morning, get to work feeling much better, and work a couple hour later than typical End-of-Day.
Is it natural for humans to wake up with the sun? It may seem so but unless you're a farmer or hunter etc I think its unnatural.
Where did this 9am BS start? Was it established ground up? Or top-down?
I am not personally complaining because I don't have to commute to work anymore, but generally I think the timing is off, not natural to our modern human clock.
