Normally I support real infrastructure building, when it is appropriate. And America has not been building airports or runways at anywhere near the rate of traffic growth. However, this is a great example of politicians grabbing money and spending it inappropriately.
These wasteful misallocations are nothing new, of course, but they add up, and add up, building our exponential debts upon one another. Creating infrastructure that builds commerce is one thing, but building infrastructure that does not simply adds to future carrying costs as that infrastructure must be manned and maintained (ht Don).
