I'd like our productivity gains to free up people to pursue their weird jazz-coffee bar fantasies and start more businesses. That's a better world to me than the the one OP is trying to get us to retreat to.
There's lots of terrible things about social media but its ability to spread the wealth of attention to small businesses is probably the best thing about it.
Bad tourists? FINE THEM. I realize the Japanese don't like to see their relationships as transactional, but they have foreigners there and managing their behavior via transactions is totally fair to me.
P.S: I know, I know I have recently been to Japan and seen its over-tourism first hand. I also don't know a country better equipped to get a handle on it and gasp scale.
