My very average house today is a huge luxury compared to the very average house my grandparents bought in the 60s. I have a cable bill, an iPhone bill, an internet bill, a netflix bill, and too many various SaaS subscriptions. My grandparents had none of those.
I also have a much higher power bill to pay for all my consumer electronics and air conditioning, a higher health insurance bill to pay for drastically better health care, an extra car insurance policy.
That's in addition to all the extra stuff I have lying around. 2 cars, not one, both of which are vastly superior and more expensive than what my grandparents had. Superior home appliances. And 1 metric tonne of electronics. I have so much more material wealth than all but the very richest did just 50 years ago. How could I complain that I'm not better off?
