"Using one-generation measures of social mobility—how much a father’s relative income influences that of his adult son—America does half as well as Nordic countries, and about the same as Britain and Italy, Europe’s least-mobile places."
Good, because of course I would want my income to influence that of my children. Yes, yes, I would want them to work hard and be curious and chart their own path, etc., but because I'm their father I'm going to try and stack the deck in their favor as high as I can possibly stack it.
And let's not kid ourselves - everybody who cares about their children, no matter what their political inclination or relative level of wealth, tries to do exactly the same thing. From the hedge-fund billionaire to the immigrant janitor.
