Around 10 years ago, our neighborhood was mandated to have our own separate boxes for mail/newspaper next to our house, but before then you’d have one group box for the whole neighborhood, with separate sections for each house. It’s much more efficient for delivering that way since you just go to one box rather than door to door, though it can be a bit annoying having to walk to the box every day to get your daily newspaper.
They’re actually given full legal immunity to anything, meaning they’re allowed to commit crimes if they so choose (which we wouldn’t know anything about as there is no transparency concerning these types of things). There have also been cases of violent repression against unarmed dissidents who were protesting against the monarchy (mostly when the queen had died), with disproportionate punishments handed out.
Is this really necessary, having one family be pretty much above the law and having their lifestyle be funded via public funds? Sure, there’s an argument to be made that it drives the tourism, but it’s unknown how much does the royal family contribute to it, as there’s definitely tourists who would still visit the monuments and buy merch without the family.
