Just so I understand you right, you're saying it's okay to violate people's rights, so long as the pay is good, your family really needs the money, and you hold some kind of internal objection to your own work?
Supposing that every person today who applies for a job today with the TSA knows about the body scanners and the pat-downs and the unexplained detentions, to what extent are new job applicants morally blameworthy for applying for a job that they already know involves all of these things?
At best, your argument covers people who applied for jobs with the TSA before anyone knew what the TSA was going to be doing at airports, and who have over the course of 18 years been unable to find work elsewhere. What share of TSA employees do you suppose that is? What's your guess?
