Like the progressivism of the 1900s, but unlike the labor movement and agrarian populism, the progressivism of the 2000s is a movement of haves motivated by pity for the have-littles and have-nots, rather than a movement of have-littles and have-nots motivated by self-interest. And because they are, or believe themselves to be, motivated by philanthropy, the progressive haves are less interested in the economic struggles of the have-littles of the broad working class than in rescuing a far smaller number of have-nots from dire poverty.
