Of course not. Some may say it's not really our job to know where our tax dollars go, "that's not how taxes work" the proclaim with ignorant indignity.
The issue is that when you dig deep enough, even people involved may not know, there are certainly very, very few checks and balances, transparency, market incentives, etc., regardless of if they know where it goes, etc. If at the end of the day your taxes go to line someone's pockets, or to get someone elected, even if they know where it goes it's entirely indefensible.
Not many things strike me as really scary about our current system (thankfully), but the idea that people on this forum (any group to be fair) would be making routine decisions about what I could own, or how much value my work was worth, would be enough to make it time to shop for a better government/society.
