I usually refrain from posting about such stuff on my site, mostly because I tend to work myself up into a rant and I just don't have the time and energy to deal with that these days, but this was a really good read. While responding to a question about a certain aspect of airline security, a pilot provided his thoughts on the industry as a whole. This is a very insightful point of view, and covers a lot of what's just plain wrong with the state of affairs today.
I highly encourage anyone interested in this sort of stuff (and if you ever have reason to fly on a plane, you should be interested) to read the full article. It only takes a few minutes.
