I mean, we could argue about this all day, no (although, the income is separated logically, which is why I made my argument in parent comment; it would take Congressional effort to spend payroll tax income on non-entitlement spending)? Sure, federal tax receipts will be used to replenish social security and Medicare, but I'm fine with that. We can afford to cut defense spending back, as we spend more than the next 8 countries combined. That's our own money being squandered.
