I'm not even sure what you're suggesting though. It sounds like you're suggesting that we should continue shaming poor people as an effective means to prevent poverty. You don't think absolute desperation and lack of safety, security, health, and food, is enough of a motivation?

No, I think ignoring the cause of the problem is not a road to a solution.
Maybe a basic income system is necessary for our society to function in the future. There are a lot of indications that this is the case.
I have yet to see even a back of the envelope calculation suggesting these benefits will occur.
