To hell with upward mobility. What is needed is a decent life for the downwardly mobile.
Upwardly mobile people are, to put it bluntly, ass-kissers. Not the talented people you know personally, of course, but in general, upwardly mobile people want to please the people above them so they too can rise to that level.
Make it possible to survive on a course of downward mobility and you unlock the real talents, of art and social service and scholarship, that are otherwise straightjacketed by the desperate need to find the next meal.
Rewarding the upwardly mobile has given us a nation glittering with toys but poorer in real terms every year. It's just common sense to help the poor- it won't be so very long before you are among them.
