I think the more import trade-offs are around availability of free time, which probably has been reduced for a lot of workers by the internet and smartphones as well as technologies that allow individuals to do things that would be either labor intensive or have high capital requirements. I can do things today on a middle class salary that only a millionaire would have been able to do in the 1980's.
