Puerto Rico's situation is analogous to Greece's. They have run up a large debt in a currency that they have no control over. There is only two options for dealing with the debt. They have to pay the debt out of their economy's savings, austerity, running a government surplus by a combination of increased taxes and reduced spending. Or someone else has to write down the debt or shoulder the debt and pay it off for them.
Both approaches have serious problems. Austerity can fail because while deficit spending boosts the economy, the converse is also true. Running a surplus required to pay off the debt depresses the economy. A depressed economy produces less tax revenue forcing even more tax increases or reduced spending which depresses the economy even more in turn requiring ever increasing amounts of austerity. If the debt is large enough and the term to reduce the debt is short enough it is impossible for the government to pay back the debt because the economy and tax revenues decay faster than than the debt can be paid back. The depressed economy produces high unemployment requiring more government spending. The net result is even more debt, not less.
Writing off the debt has the problem of creating a moral hazard. It encourages the bad behavior, running up the debt, that created the problem in the first place. For example, relying on government debt decreases temporarily the pressure to collect taxes. Increased government spending is always welcome but the rigor of tax collection is not so welcome.
The obvious solution is to combine the approaches, to write down part of the debt or to transfer part of the debt to the government that controls the currency that the debt is in, to lengthen the term of the debt remaining so that the impact on the economy in any one year isn't too serious. To let inflation write down the debt over time. To cause enough pain to avoid the moral hazard, but to reduce the debt, the interest rate and the term of the debt to avoid the cascading, 'surplus producing a bad economy reducing revenue' problem with austerity.
What is standing in the way of implementing this obvious solution? An almost perfect storm of bias, flawed thinking and misunderstanding of the economics involved. For example, belief,
- That government debt is the same as personal debt.
- That government spending has little or no impact on the economy.
- That the economy is supply side driven.
- That the best way to a good economy is to increase investment by directing money to the rich and away from everyone else.
- That the money loaned out by the banks is the depositors' money or the banks' money.
- That money is a desirable product of the economy.
- That sovereign governments can save money as in the opposite of debt, for example, a lockbox for excess payroll taxes.
- That government debt is always an evil unless it was built up by lowering taxes.
- That government is evil, is largely not needed and only harms the economy.
- That private enterprise can do what government does better and cheaper.
- That the cause of the high debt was profligate, unnecessary spending.
