Wonder if he consulted any of the models in his widely used Macroeconomics textbook in order to reach this profound conclusion.
I think an even better way to help people right now would include Congress putting an end to the price gouging of students who are forced to pay as much as $200 dollars a pop to purchase textbooks (like Mankiew's Macroeconomics) for their classes.
And there's an idea for Bernie Sanders too, who is gasping for breath on the campaign trail now: instead of promising "free tuition" handouts, how about asking government to play a role in establishing "fair tuition" (much like Medicare already does in health care for seniors) that reflects the true costs of educating students (using the latest technologies) in subjects that lead to real jobs, after universities have been forced to cut the fat (starting from the top!) out of their bloated university administrations.
