There is undoubtedly a link between white poverty and white identity crisis but there are a couple problems here. First, there is the rather gross subjective assessment of this person’s home. https://twitter.com/walkerbragman/status/1314343175960567808

What is supposed to be so dismaying about it exactly? It’s a house...on a rural road. A lot of people live that way (and not all of them are white) and most of them don’t turn into terrorists.

And there is actually a lot of agreement that white poverty, especially rural poverty, has the same culturally deleterious effects as Black “urban”‘poverty. There are entire fields of study about it that care about misplacing causal mechanisms

But the real issue is that he has no basis for economic poverty or deprivation as even being true in this case! It’s only evidence of cultural poverty which says more about the one doing the assessment than it does about the person being assessed.
