Uhhhh....tax revenue aside, the only thing that adds to the debt is gov’t spending. When your income changes, you adjust accordingly.
If people pay less taxes because high-income jobs go overseas, the government doesn’t have that money to waste. Besides that, many of those people who lose jobs collect food stamps and other freebies. They cost money and that adds to debt. Our government does not adjust accordingly when they have less revenue, thus uncontrollable debt has occurred.
