No, they correctly identify it as learned helplessness which is a real behaviour common to many animals including humans. If you experience repeated misery, set backs, abuse, discrimination, and even just bad luck it conditions you to believe that no matter what you do you will always fall victim to the worst outcome so you just give up and stay where you are and endure it the best you can. That is not saying that the reason people are poor is due to that conditioning, it’s saying that they were conditioned to act that way because they were poor and now even if you provide them a way out they are so beaten down and demoralized that they will just stay where they are and not even try. It’s almost impossible for people who have not experienced that level of abuse to imagine what this feels like or follow the reasoning behind it.
