Message to Republicans: if you cut spending on "worthy causes" to zero, you still would not balance the budget. You will have to raise personal income taxes.
Message to Democrats: if you increased personal income tax receipts by 25 percent (a ginormous tax increase), you still would not balance the budget. You will have to cut back on "worthy causes."
Message to the AARP: if Social Security and Medicare continue to be "untouchable," then y'all had better buy guns, because in twenty years there won't be any money left to pay for national defense, much less for any "worthy causes."
