1970: 36% of all households had air conditioning.
Today: 83.95% of all households and 78.3% of poor households have air conditioning.
1990: 15.7% of all households and 4.9% of poor households had a computer (and I'm sure close to 0% had one in 1970).
Today: 68% of all households and 38.5% of poor households have a computer.
Similar massive improvements can be found in all
sorts of things which affect quality of life. Almost all poor people have refrigerators now, while in 1970 lots of people didn't. Lots of poor people have cell phones now, only the uber-rich had them in 1970 (and those weren't near as good as the virtually disposable phones you can get now). Medical treatment available even to those on Medicaid often didn't even
exist in 1970, no matter how rich you are. And on and on and on.
