On The Glenn Show, Glenn and Harold, inspired by a recent NPR series, discuss the startling rise in the number of Americans on disability insurance. They ponder the best way to define disability, and use the parable of the “dog bone economy” to examine the position of marginal workers. How should Medicare deal with the divergence in longevity between rich and poor? Glenn offers a libertarian rebuttal to Harold’s arguments about the moral claims of less productive members of society. Finally, they examine the retirement savings mess and explain why you probably shouldn’t listen to your investment adviser.
