Corporate Jets

This is something that has been bothering me for a while. Recently the attention given to this matter has risen to a level worthy of discussion, so here it is: why are people so disgusted by corporate air travel? When GM, Ford and Chrysler CEOs went to Washington for hearings few weeks ago, no one could stop talking about the fact that they each took corporate jet to D.C. for the hearing. There was nothing but outrage and indignation at the fact that these execs were begging for money but were "wasting" tens of thousands on corporate air travel. How arrogant that they can't travel commercial along with the rest of us sacrificing peons without stock options. At the very least, don't they have a PR person whispering in their ear that it would look bad?
