Over half of that $20 trillion was added over the past decade.
And it looks like annual deficits will be at the trillion dollar level sooner than later when projected spending is factored in.
Basically, the United States is going broke.
I don't say that to be hyperbolic. I'm not looking to scare people or attract attention to myself. It's just an honest assessment, based on the numbers.
Now, a $20 trillion debt would be fine if we had a $50 trillion economy.
The debt-to-GDP ratio in that example would be 40%. But we don't have a $50 trillion economy. We have about a $19 trillion economy, which means our debt is bigger than our economy.
