Most of the money goes to Social Security, Medicare, and the military. I don’t currently benefit from the first two, but I will if I live long enough. (Reports of SS’s demise are exaggerated. The worst case when it runs out of money is that benefits are cut, not that it disappears entirely.) The benefit of the military is debatable but I would argue that there definitely is a benefit, although we spend a lot more than we really need to.
