"industry insiders were ringing the alarm bells" Just as today many economists are ringing the alarm bells: the governments public debt issues (both in U.S., Japan and many countries in the Eurozone) are going to end up very badly. Many central banks (including in the U.S.) have basically become bad banks. Anyone holding medium and long-term public government debt (like many insurance products) are basically bankrupt…
In plain English--the government is taking a smaller piece of a smaller pie. No wonder our debt level has climbed.
And yet U.S. Treasury bond rates are still extremely low--which indicates that people are still very eager to invest in them. Why? Because despite obvious problems to solve, the U.S. government is still more secure than other options. As long as that is true, we can continue to finance.
So to talk about doom and gloom, you need to make a case for where all the money will go if it abandons the U.S. The typical candidates have been Europe or China. Well, Europe is in even worse shape, and China is heavily dependent on the U.S. for its own growth.
