ROFLMAO.

If you don't fix the policies, they just hire replacements. You even admit it is how it works.

"The strategy seems to make a lot of TSA employees feel bad, so the turnover there is quite high, but enough people need any job just to make ends meet that the overall effect to their workforce isn't very much."

You also didn't think about the logical result of pushing out the people who would feel bad about bad policies. It means you leave only the desperate & the bad people running the organization. Well done! You've removed everyone with a hint of moral fiber and/or soul from the enforcement role. And then you'll be surprised when no decent person is there to help you when there is an issue.
