Anglico linked to this strange article by everyone's favorite arch-conservative John Hood that decries public transportation because it is not proven to lower obesity levels. (WTF: I guess he just needed some strawman today) But I only had to read his openning sentence to see his true uncaring character:
Because we have taxpayer-financed programs such as Medicare and Medicaid, obesity is a major public-policy issue.
You see John Hood, and others on the extreme far right with him, only thinks that the health of citizens is important when it somehow affects their personal pocketbook. To me working for the common good, including good health, is a fundamental public policy position that should be pursued regardless of whether I personally see a benefit from it or not.
