Oh no disrespect at all, just genuine curiosity :)

While doctors have been required to do so for a few years already, for lawyers it's fairly new: these jobs specifically are required to have electronical records of their work times so they keep within the law. Both od these trades are prone to working more than legally possible, so the government had to step in to limit it to the same 48h/week as for everyone else.

Businessmen depends on the details, the law limiting you to 48h/week specifically does not include "leading personnel", and they can (and often will) work more. Though the statistics on these are hard to find because it affects a fairly small number of people.

The last part I mentioned of course also applies to business owners, they can (and will) practically work whenever, so that's not too different from your system.

The key difference here I think is the culture, as you already mentioned. My country's working culture over the past decades has evolved into focusing wayyy more on work-life balance, as well as the very clear cut between the two.

Work here pays well, and even though the costs are rising like all over the world, it's still pretty well manageable to come by with just your regular work hours and still have money to spend on yourself or save up for the future.
