- People working more hours
- People moving more frequently
- Reduced home ownership rate
- Lack of reciprocal interdependency: people don't "borrow hedge clippers" anymore
- Deference to contractors and service providers over DIY*
- (Discounting religious aspects) Downfall of church as the basis of local community
- Fear of other and strangers promoted by mainstream media
- Status snobbery increases greatly in a society where material needs are satisficed
- It can feel like wasted effort or carrying the relationship to arrange social gatherings and parties when there is a lack of reciprocation
* As far as I know, I'm the only one on the block who can operate wire strippers, soldering iron, backhoe, auger, vehicle jack, air compressor, angle grinder, and sourcing specialty items (sometimes from overseas). Most of the people on my block are introverted game players, TV watchers, and don't have many hobbies. Meanwhile, I'm bugging my second cousin for single prop Cessna engine hours over at thriving aero sales and training school in between doing PPG which doesn't need any licensure in the US.
