Why do people accept this reality when talking about the TSA, but not other government agencies? All government agencies are like this, especially the Federal ones.
The TSA is also an obvious waste. They aren't that much different before hand although, their function were covered by a hodgepodge of regulations usually dictated by the FAA and private airport security employed at airports US wide.
The upper-middle class tends to set the agenda for the media in general. They're also the archetype of what are depicted in TV shows and so on. Why the recent school shooting became a national outrage is probably because they were a middle class school. The death toll also added to it.
