A technique of politicians deploring any change to Social Security is to paint the picture of an old lady forced to live on cat food. I was always somewhat dubious of that pitch, I figured cat food might even be more expensive than other sources of protein.
In an attempt at investigative journalism, I checked prices on cat food versus tuna (a close human equivalent) and find the shocking truth.
It turns out that the politicians were correct: it is indeed cheaper to buy cat food instead of human food. At my local supermarket, the price of five ounces of cat food was 89 cents; the price for five ounces of tuna was $1.17.
While I am unlikely to change my views on Social Security, I may reconsider my purchases of tuna. The cat food is cheaper and probably has less mercury.
