You named 3 theories, not 3 real world effects. I don't like deficits in principle either. But I also don't like welfare programs such as social security where plenty of people are getting far more money than was ever put in by them (not to mention all the people who get it without having worked a day).
The graph I posted i think makes the case pretty succinctly. It's the redistribution of wealth programs that are gobbling up the budget. Not interest on the debt.
