Why should the wealthy or the upper middle cl suffer some inconviniences for the welfare of the rest?

And who are you to dictate to someone what their morals and values should be? These rich and upper middle cl often give more to charity than you'll ever know, despite the fact that the people who are being helped by their generosity do nothing improve their own situation. Eventually, the host will have no more to give, after which, both the parasite and the host will die.
