One is a systemic condition that requires changes from society, the other is a temporary condition caused mostly by factors under your control. Confusing the two encourages ineffective 'solutions' for poverty to be created like 'we just have to make it embarrassing/uncomfortable/illegal to be in that condition'. These rely on motivating the poor person to fix themselves, instead of attempting to fix the surroundings that are the actual cause and address the symptoms that the poor person is unable to fix on their own, and then dismissing the ones that don't bootstrap themselves out as lazy and undeserving.
