With the adoption of a healthier American lifestyle that the White House Garden models, we could knock a serious blow to two serious concerns: obesity and spiraling health care costs . All for $200--the reputed cost of installing the White House Garden. Labor is on a volunteer basis and free unless you count in the cost of Sam Kass, the official garden keeper. Sure there are plenty of externalized costs that Obama detractors will be happy to calculate. Like the costs of those cute yellow t-shirts the school kids all wear. But given our frugal times, this can be held up as a paragon of government spending on any cost-benefit/impact analysis spreadsheet.
