Apologies for the earlier snark (feeling a bit punchy today).
Though I do disagree with your point. Perhaps what you say is true, that if passengers take up the slack and make the TSA line more efficient then the TSA will reduce staffing. I have no problem with that - that means the TSA won't be as big a burden on the tax payers. Yes, the TSA will still probably waste a bunch of tax payer money, but at least they will waste less of it.
