The "back of the bus" has turned into the back of the plane — with discrimination based on class, social status… and money. When airlines sell more seats than a plane will hold, they're allowed to force one paid passenger to give up a seat to another.

With just four main carriers left because of consolidation, passenger service is a casualty of the drive for profit and America's increased wealth inequality.
