I think it’s the same in all developed nations; constantly needing more skills to achieve the same standard of living. I think a lot of it is from nearly all resources getting more expensive to extract (oil, wood, iron, etc) due to us having already extracted all the low-hanging-fruit, and needing to move on to more resource-intensive methods like offshore-drilling, fracking, importing lumber long distances from harsher climates. The other drivers are the attacks on labor and executives/shareholders taking more profits for themselves instead of paying their workers more.
