Well, first the US gov cannot "focus all of its income on debt repayment" any more than a household can. The real question is how much unallocated income can the Fed free up by cutting public benefits before the recipients of those benefits vote them out of office, or, in some cases, shift critical campaign donations to their opponents? Politically, those vast unfunded liabilities are much harder to default on or inflate away than the public debt. You can cheat the Chinese easier than you can cheat the Social Security and Medicare recipients.
Second, if every private and public entity in the US sold off its assets and magnanimously donated the proceeds to bail out the national government, who would buy all that stuff while all the potential buyers are selling? it is just as if everyone in the stock market decided to "cash in their chips" at the same time. They could not really obtain the nominal value of their assets. This is known as the "fallacy of composition." The other problem is that the present value of the Feds' total unfunded liabilities, not just the official national debt, is now in the neighborhood of $200 trillion. In addition, states, counties, cities, firms and other private entities, and households all have substantial debts as well. This problem is not exaggerated.
Third, just focusing on the narrow problem of the official Federal "debt held by the public" for a moment, it is a historical fact that countries that accumulate a public debt greater than 90% of their GDP have had a very difficult time avoiding reduced growth rates and financial crises. I highly recommend Kahneman's book "Thinking, Fast and Slow." One issue he deals with is that we all tend to rationalize why we will beat the odds, such as finishing a project much faster than others have finished similar projects, or why real estate prices in our city would not crash even if they did everywhere else, or why we can cope with debt burdens that have crippled others. What we ignore is that others usually had their own reasons why they were exceptions to the rule. This time is not different, we are not exceptional, and people who think this way are usually deluding themselves.
wrong. US politicians will take a leaf out of the playbook of Maduro , dictator of Venezuela, to pacify the whining American public. they will inflate the currency and impose more socialistic measures in order in theory to help the average man and the so called poor class. the masses will cheer these measures to bring about equality until these measures fail. starvation as in Venezuela will ensue. hard work productive American workers will flee across the border to Canada.Politically, those vast unfunded liabilities are much harder to default on or inflate away than the public debt.
you are right America is not exceptional. they will fall for the delusions of socialism. they will suffer the consequences.
