One topic I almost always cover in talks is the demographic shift in store with the aging of the Baby Boomers. Now the Census Bureau comes out with a report that the aging of America isn't going to be as much of a problem as we worried because older Americans are getting healthier (and richer, and better educated). So, to bring Social Security back into balance, we should raise the retirement age at once.
"Seldom does justice so perfectly suit convenience. Raising the retirement age would honor the principles of productivity and self-sufficiency that originally defined the age group deserving of benefits."
