David and Mr. "almost 2 people die every second" both miss THE key point illustrated by the response to the attacks on 9/11.
The people at the top of those buildings were some of the wealthiest people on the planet. If they were dirt-farmers in Sudan or Ethiopia, we'd be all maintaining our calm perspectives. But when they're multi-millionaires in NYC, then we need to do something drastic.
The idea that all people are of equal worth and value is a nice idea, but it is not put into widespread practice. The way our world allocates resources, 1 NYC bond trader or better yet, a Goldman Sach's senior partner could easily equal 1,000 Oklahomans or 5,000 Okinawans or 50,000 Columbians or 1,000,000 Sudanese or 2,000,000 Congolese. Perhaps there's a need for a human worth calculator web-site...
So, if we have to crap ourselves in coach class on airplanes 100 times a day around the USA so that a single Goldman Sachs partner has a 0.000000000373% lower chance of being a victim of a plane falling out of the sky and landing on his yacht (he would not be caught on a commercial flight), then so be it. It's a fair trade.
