Wallis ought to read The Tragedy of American Compassion by Marvin O'Lasky if he wants to read about the proper approach to alleviating poverty. The welfare state mind set leads to generational poverty and hopelessness. Wallis is a product of the 60's generation who can never seem to get over themselves or admit that their cure for what ails America was nothing more than Marxist snake oil.
They don't want the cure, they want power. To get power, they must have reliable followers. One way to get people to follow is to make them dependent on you. So to ensure a never-ending supply of reliable voters and useful idiot demonstrators, the leftists have to make sure that poverty continues. To increase their hold on power, the leftist elite must even make poverty worse, or at least try to persuade everyone they can that it is on the rise, even if it isn't.
