When looking at median wages and median household income from 1980 to 2015:
How does the inflation data take into account more expensive production methods that lead to far less pollution, giving us all cleaner air, rivers, etc.
How does inflation data take into account more expensive worker safety equipment and safe work practices, leading to far fewer worker fatalities and injuries.
How well does inflation data take into account college cost increases due to fancy student rec centers, better student health facilities, and more student services?
How does inflation data take into account the effect taxes have on prices and rents (such as real estate taxes), allowing us to have far more government services, such as more police and better roads, which keeps us all safer (but will be reflected in higher rental prices).
How well does that inflation data take into account brand new technology that never before existed that leads to significant improvements in quality of life?
How well does that inflation data take into account much safer cars, leading to 66% less traffic fatalities per mile traveled?
How well does median household data take into account changing characteristics of households themselves, with far more households containing only a single adult?
These are just a small sample of the things the data you post doesn't capture. What matters is people's actual quality of life and the things that are relevant in determining what that quality is. Digits in a bank account are a means to that quality of life, but they are not the quality life in and of itself.
No matter what is taken into account, all of the classes get to enjoy the things you mentioned, but only the upper classes get to enjoy those same things PLUS rapidly rising income. That's the elephant in the room.
