Every generation thinks the one after it is more rebellious, selfish, blah, blah, blah. I don't know. I enjoy my kid's company (31 and 28) and their values aren't so different from mine. Sure, they've had vastly different experiences, but still. I prefer them to some of my so called friends who just seem old. More like my grandparents!
I sort of agree with the growing population of humans issue; I can't quote evidence, though. I get upset when I see someone having 3 or 4 kids, even when they can clearly afford them. Of course, it's my personal bias, because I could have never handled 3 or 4 kids in my house.
