The first line was a bit off the mark depending on where you live. Around northern Cal (not sure about down south) the houses are big and are often being rented to multiple families of anywhere from 5-8 members each, because that's what it takes to keep a roof over your head.
More conveniences, less time, I agree. It seems to me because if you do anything to free up your time, life seems duty-bound to rush in and fill it up with something. Some people se idle time as a sin and not as a deserved period of downtime, a reward for working quickly and efficiently.
More knowledge, less judgement: Okay, even in Dungeons and Dragons a person can have a high Intelligence Score and a low Wisdom score, so no argument there.
More experts but more problems, because many of these "experts" are guided by trends and not wisdom or knowledge.
More medicines, less healthiness: If it's easy to get well, then why worry about getting sick? It's people's mindsets that need healing, not their bodies so much. A little education wouldn't hurt, either. There are places in the Third World where people still think it's okay to drink from the water supply that they use as a toilet.
I'm out of time to post my opinion on this (yeah, that part about time and conveniences...), but I believe people have gotten too used to instant gratification and "what's in it for me?". Why should I go meet that neighbor? What's he done for me? Why communicate anything of substance when I have the anonymity of my computer to allow me to vent my frustrations in an immature manner? Mass media has also convinced us that we need to be entertained 24/7, that we have to be where the action is, and generally has downplayed quality in favor of quantity. We are creatures of our enviroment, the one we created and the one we accept. To fix this, you have to fix people. But, to quote Bill Engvall, "You can't fix stupid."
