Surely, Social Security is important enough to merit multiple anniversaries.

So it is that over the weekend we celebrated 75 years of monthly benefit checks. The agency sent its very first on January 31, 1940, to one Ida May Fuller in the amount of $22.54. (That’s $372.81 in 2014 dollars for members of the Good Old Days Club.)
