Against Raising the Retirement Age of Social Security

This 'bloggingheads' video provides my view on raising the retirement age of social security, which is that this discriminates against those who work at manual labor jobs, because they die earlier and retirement is forced upon them at an earlier age because of the heavily 'physical' nature of their work. Plus they simply need the money more than those in more professional/white collar/entrepreneurial work.  Robert Wright provides the arguments against the seemingly clueless Mickey Kaus.
