I don’t know the funding for Pre-Check, but it does work great at airports and does greatly speed up getting through TSA, so the net effect is less need for TSA people...so probably a net positive, but still very small numbers overall.
Well, I can say with authority that I would rather have a simultaneous root canal and IRS audit than fly. And even if I had to, I would never avail myself of PreCheck’s services. It’s bad enough government has my info, I’m not giving it to a private company.
But if other folks want to, fine by me. As long as their fellow taxpayers AIN’T paying for it. :-)
