That it's a near minimum wage job is not actually the fact though. Even the minimum starting salary for an entry level TSA position is higher than the highest minimum wage of any city/county/state in the US. The median TSA salary is also a hair above the median of full time salary in the US.

For the most part I agree most are at least neutral though. I.e. they are there because it's a job, not because they hate people or love people and this job was the way to do that. It's just the ones that do tend to really stand out for people.
