I'd like to suggest an alternative to bashing the TSA. (most of the comments on here)

Let's invest more in non-road infrastructure. We need bigger airports, faster trains, better mass transit connections to these hubs.

Airports are over capacity in the US. I was in Chicago O'Hare yesterday, there were about 100 people sleeping on the floor throughout terminal B and C. When my flight boarded, nobody got up from their chairs, since they were waiting for a different flight, at a different gate, where there was no seating. Not only that, the roof was leaking, there were 10-15 buckets dispersed in the terminal catching rain drops from the ceiling. This is potentially the most important air transportation hub in the country and it is crumbling. There are plenty of other examples of this around the country.
