The conditions and forces which make those poor people dysfunctional are structural and by design. Keep them unhealthy, subject to bad food and conditions, poorly educated, and pumped full of media BS, and naturally they'll behave badly.
I'm not trying to inject WV into the forum but I mention it for comparative purposes, and it is instructive because we have there a subset of the USA which suffers high levels of poverty and dysfunction, and are overwhelmingly white. I look at their behavior and it makes me feel ill. The grandchildren of farmers who watch grandpa's tractor rusting in the field while they eat junk food and complain about the unpicked fruit which falls and rots on the ground.
I just have to remember that I'm university educated, we got out of WV young. I grew up in affluent suburbs of Pittsburgh and L.A., so they perhaps rightly dismiss me as a pointy-headed smartypants outsider if I criticize what they're doing in WV. So I end up having the same view you express. that they are willfully dysfunctional and hurting themselves.
The rich of course are behaving rationally. They have to in order to preserve their position of privilege, which requires a lot of manipulation to pull it off.
