Uncensored was referring to the purchasing power to support a lifestyle, back then vs now. We are all well aware there is huge income inequality, but that is not what he was speaking to, and not what the tables shown get at either, as lack the historical perspective. We're not talking about a 20 year perspective as income inequality has spike, but really lower middle income purchasing power to support lifestyle late 50s-early 60s vs now.
A low income single provider, could probably have a similar lifestyle to early 60s in a rural area, but early 60s was before cell phones, computers, air conditioning (for the most part), telephone might have been a party line, and maybe one vehicle for the family. Although typical back then, it would be pretty primitive to most people now. He says today's low income (I assume above poverty level) can buy a higher lifestyle than back then. I don't know. I certainly would not want to live that way and start a family, certainly not making extra allowance for a stay at home mom to raise the kid or kids at that income level in this day and age.
