The premise was that nobody but people who work support higher taxes. It was that people who don't work probably support higher taxes, because they get benefits with no cost to them personally. It doesn't matter what the TSA does - the fact is they were invented as a response to terrorism. Thus removing them would be an opportunity for an opposing politician to use the attack of 'being soft on terrorism'. I think the TSA should be abandoned - I shudder to think of the lost actual dollars in funding, as well as the lost productivity of millions of air travelers going through a couple of minutes of invasive screening. As for 'prevention' - many western nations have been victims of Terrorism attacks since 2001 - including the UK and Spain. None of these countries have/use TSA style screening or restrictions. None have had an airline-based terror attack since. That should tell you about the need for the TSA.
