You're completely missing the point, but that's not your fault. There's a little known "phenomenon" (that was previously posted here on HN) about the almost matching prices of a pizza slice and the price of a subway ticket: http://en.wikipedia.org/wiki/The_New_York_Pizza_Connection
"He noted in 1980 that from the early 1960s the price of a slice of pizza "matched, with uncanny precision, the cost of a New York City Subway ride."[1]"
Nice. My theory is that the color of the sauce on pizza in Manhattan is directly correlated with the color of subway services that run on the IRT 7th Avenue line. It's been true even longer than the price thing you cite.
The difference in the two situations of course being the the colour of pizza sauce and subway services is constant, whereas the price of the ticket and the pizza slice are both variable over time.
It suggests that both values are tied to the same index somewhere - for example maybe both the government and pizza places have tied their pricing to be 0.1% of the average monthly wage. Or maybe it's tied to the price of crude oil. Figuring out the common index may give valuable insight into government services pricing and pizza making...
