The major check against the unreasonable, horrible practices on the part of the TSA is that people who fly are wealthier, on average than people who don’t — and people who fly a lot are wealthier still. That meant that the worst stuff the TSA did was felt disproportionately by people who had a lot of political juice — people who get listened to. Increasingly, though, rich people can opt out of the worst of TSA treatment by buying voluntary background checks and bypassing the rigmarole of the plebs. Now, the TSA is expanding its Pre-Check program, ensuring that pretty much everyone with any political clout will be spared the worst of it, letting the TSA’s treatment for aviation’s 99 percent spiral steadily downward, moving from mere Security Theater to Security Grand Guignol.
