For me it's very strange to see that a huge portion of the population sleeps until 9am (and a big number even until 10am!). I worked in many countries before and in most workplaces you had to show up at least by 9. Of course there were some exceptions but in general that's how it was.

Yeah, well there's a lot of businesses that operate late into the night. You think 24/7 pharmacies, retail, restaurants, etc operate themselves? There's also emergency personnel, security, even night construction crews.

You have clearly worked in ‘white collar’ environments.

2-10 or 4-12 shifts frequently involve waking up at 9 or 10.

I think it also depends a LOT on if you're an early / late morning or even night person.

I find it much easier to stay up later than to wake up earlier; for others it's the opposite.
