I've seen more than a few threads here where the OP is wondering how or why other people in different set-ups to their own (poorer/richer/more or less family interaction/different schooling methods/whatever) live the way they do.
Sometimes the question is rather obviously an excuse to rant and be judgey, but sometimes it's an honest question - like 'AIBU to wonder how families with such-and-such an issue deal with it?'
In many cases the OP is simply told it's none of their business and to f* off.
The thing is, sometimes I wonder these things about people outside my own circle of family and friends, whose situations are different to mine. For me, most of the time it's simple curiosity. I sometimes watch reality TV shows (which are proverbially none of anyone's business, IMO) for the same reason.
So AIBU to think that if you're asking a general question to a general audience out of honest curiosity, you should be able to hope for an informative respnse rather than 200 lots of 'None of your business'?
