Earlier quoted context omitted.
> payroll taxes don't fund those It's kind of silly to make the distinction between which taxes fund which programs. It's completely arbitrary. Dollar bills are dollar bills
But for the fact that those dollars literally do not pay for roads and, when roads need to be built, those dollars will not be appropriated to do so. Other than that you're right of course, totally silly, what was I thinking.
At the end of the day if bills get bigger I can always pull money from gig B because I own the income stream. Just because I can currently accurately apply these arbitrary labels doesn't mean those labels aren't arbitrary, and it doesn't dictate what I will do with that money in the future.
It would be a bad idea for the owner of the income streams to actually make spending decisions based on the size of each income stream. You should always choose the expenditure with the highest expected value.
