One problem for adults in the US at least, the center of gravity for many institutions is on the East Coast, New York for finance or DC for the government. Huge numbers of people on the west coast start their workday at 6a or 7a to align to accommodate east coast peers or organizations. If the European settlement of the US had been done in reverse, I can easily see a world where Virginians are regularly staying at work till 8p because that’s when their customer is available.
