Your parent probably meant dirty in a very physical way, not, as you seem to have taken it, a demeaning way. I don't think of "dumb" when I hear "dirty"; maybe the popular Discovery TV Show "Dirty Jobs" is a reason for that.

Also, while I've never been to Norway or Netherlands, I think you're underestimating the number of "dirty jobs" that support you. Who's tilling the land? Mining the minerals? Excavating land? Driving the garbage trunks? Emptying the lobster traps? De-greasing the engines? Tending the public spaces?

I'm not against legalized prostitution, but I think its a strong strike against any claims of higher responsibility towards society.

Yes, many of these things might be automated one day, but that seems far away (a century at least). Your parent's question is valid and, as far as I'm concerned, there's no place on earth that comes remotely close to what you seem to be describing.
