Fly 2nd class? He can certainly fly 1st class - ON A REGULAR FUCKING PLANE, not his own fucking lear jet.
His behavior exemplifies the elitist arrogance of the rich and powerful dictating that WE must make sacrifices to avert "global disaster" (hysterical hyperbolic bullshit in itself), while he does whatever the fuck he wants - and is "entitled" to it. Fuck him.
You just don't get it. Your buddy Bush will not be flying first class anywhere after office. He gets a special flight with secret service folks. That's the way things work in the USA. If you feels so strongly about the general issue then surely you would want Bush to take a regular flight like everybody else. Why don't you demand that too?
