Rick Perlstein over at the Campaign for America's Future is keeping a watchful eye on a growing epidemic of sinkholes opening up all over the country. Decaying water and sewer pipes are to blame. Yes, sinkholes. Yes, in America. Yes, it's weird and gross. Perlstein also makes the connection to the anti-tax movement, in the sense that a smaller tax base has diminished the capacity of government to respond to public needs, like having level ground that doesn't cave in. There's something absurd about the sinkhole epidemic, though I can't quite put my finger on it. It just seems a little over the top that the ground must open up beneath us to demonstrate that public investments in infrastructure matter and that taxes make it all possible.
