Yes, the U.S. should bail out the commonwealth of Puerto Rico on its $1 billion debt obligation. If Puerto Rico defaults, it could cause a ripple effect for the economy, causing further problems for the people who live on the island and who haven't been paid for their work. It could also cause problems in the stock market at a time when the market is already reeling from the effects of the British exit from the EU.
Puerto Rico is part of the United States despite not being one of the states. The citizens of Puerto Rico pay taxes, vote in elections, and other wise contribute to the economy and culture of the United States. Puerto Rico should be afforded the same support as other parts of the United States.
There are many roadblocks preventing Puerto Rico from recovering their economy and as a U.S. territory, the government needs to help them. Some of the issues are legislative roadblocks and some are investments needed to enhance tourism and health care and jobs. Puerto Rico is also important as a strategic location for our military.
The government has a poor track record of bailouts that do not produce satisfactory results for the economy, with the big 2008 bank bailout being a good example. Puerto Rico has just announced it intends to default on its debt even with a bailout, so there is no good reason for the US to ignore taxpayer wishes and misuse taxpayer money again.
