Don't discount the economic impact of a human emotion. The entire global economy operates on what billions of humans want, and a good portion of them don't even need most of the things that they want.
We have an entire industry--advertising--devoted to making people want more things.
So something like envy, which is to say wanting something that someone else has, is a significant driving factor behind economic activity. Mental suffering and physical suffering amount to the same thing: unhappiness with the current state of affairs. It does not matter if one person wants to not die of cholera while another wants a new smartphone with a faster processor. It only matters what that person is willing to do or to forego to get that thing.
The first person may be willing to spend a week with a shovel in a pit filled with sewage to get adequate sanitation for the rest of the year. The second person already has a flush toilet, complete with sewer and treatment plant, so maybe they're just giving up new tires for their second car.
All of economics is just individual humans making choices about what they want.
Poor Americans have been told throughout their lives that they can have a certain lifestyle--pretty good in comparison to a lot of other countries--if they are willing to follow certain rules and spend some time working rather than playing. Many of them are finding that to be a lie. So perhaps they are suffering instead from a perceived betrayal of a social compact? Everyone willing to produce shall be able to consume in equal measure?
What I am seeing through my biased eyes is that significant limitations are being placed on ordinary people's ability to produce valuable goods and services, and so their ability to consume is falling below that required by their former customary standard of living.
