Serious question: At what point does the failure of government services warrant the partial withholding of taxes? This isn't sufficient of course but when the FAA repeatedly demonstrates incompetence, when do we eventually just tell them no, you can't have any more of my money, you're obviously wasting it and making us worse off?
Especially when evaluating the FAA would need to include the absolutely stellar commercial aviation safety record they and the NTSB have created over the last few decades.
