What you should worry about are two things, regarding value:

1) You should worry when your country produces significantly more "money" than your country produces value. See Bailout Bill (I fail to see the value produced in writing up $700 billion taxed on firefighters and teachers).

2) You should worry when organizations like IMF and the World Bank extend loans to these other countries, jack up in the interest and take up more than half of the country's budget on the interest instead of the principal. Most of the countries we "help out" end up becoming more impoverished after we extend a loan to them, and much of what we build ends up doing more harm than good. Worse, the money does not even exist in the first place.
