When did I try to change the industry by interacting with the airPORT employee? I provided feedback via stern conversation with the airline rep, whatever little/nothing that does. I also strictly do not check a bag any more, so am no longer within that cost cycle.

The airPORT employee is not in the cycle you are inventing in your head. He is entirely separate from it, and benefits nothing at all from the airLINE practices.

The airPORT employee operated without any assumption of reward beyond a "thanks", so his actions were free of financial feedback, because they were decided prior to knowledge of monetary incentive. Further the airLINE is not aware of, and did not profit from his action, so my tip did not 'enable" their practices, as the only information they digested from the exchange is my criticism of their failure.

Read the room dude, you don't always have to agree with the crowd, but you're obviously wrong on this one, and I'm all done talking to you
