I'm not sure it is in the interests of the kinds of players that keep people poor to do so. They mostly just seem to be taking advantage of whoever they can without motivations in that direction. For example the medical industry grabs peoples money, which causes quite a lot of poverty, because they like money, not because they want their customers poor. Is there an example of an industry that does want people poor? I can't think of many examples - maybe in apartheid South Africa it was in some of the whites interest to keep the blacks poor as cheap labour but I don't think that kind of thing really applies in the US?
