The subtext of this argument is 'poor people have no morals, therefore they are always criminals and would never be heroes.'
Well, the flip side of this is "Rich people are evil." Which doesn't work either, AND which is what Marvel seems to be all about since CIVIL WAR. The "evil Pro-Regs" were all upper class (some exceptions like Ms. Marvel and James Rhodes being from the military). The noble Anti-Regs were from "lower class" backgrounds. Captain America calling Iron Man a "pampered punk" cemented this.
