The goal of raising taxes on the rich isn’t merely to promote equality by redistributing wealth. Rather, it’s about generating more revenue to invest in policies that enhance the mobility Ryan hopes to achieve.
“How do you increase mobility at the bottom? You provide low income families the tools to compete in a 21st Century economy,” Smeeding says. “Create revenue to invest in the mobility of kids from poorer backgrounds — improve early childhood education, improve schools, improve chances of success, lower the cost of college. He misses the whole point about mobility, which is about increasing educational and economic opportunity.” (via Paul Ryan’s solution to inequality helps the rich, does nothing for poor - The Plum Line - The Washington Post)
