Fewer jobs offer job security and decent pay. Because of less job security, you need to be in a market with many employers (aka cities), and this results in more people living in fewer places, which means higher rent.

That translates to needing higher pay, or at least a career where you can outpace rent and insurance costs. There are some manual labor jobs that pay well outside of cities, but you have to watch out for the condition your body will be in since people live longer and there will be less of a social safety net for when you are disabled and/or are too old to work.

Bottom line is more and more people are less and less valuable.
