Ah, yeah, I should say my opinion is entirely based around my experience as an American. It's pretty deeply ingrained here- I mean imagine telling an American that they have to tolerate children running around at 9pm in the dark, they can't drive their cars around because the streets are clogged with those children and furthermore, they need to stock up on candy because they will be giving it away to the kids.

And there is a culture tradition of vandalizing the homes of people who are stingy about the candy.

If it were new here it'd never even catch on, just like public libraries.
