A partial explanation could also be that they grew up in poverty because their parents were too genetically stupid to earn good cash / living within their means. I think this hypothesis is supported by adoption studies.
And a partial explanation for why you believe this is that you've been indoctrinated and propagandized and peer-group socialized into believing this. See the studies that compare incomes between adopted and biological children and adoptive and biological parents. Environment is by far the determninant.
