Does anyone else feel like this economy is unsustainable?

It's been in the news that this past quarter saw something like a 9% jump in consumer spending. I thought to myself, "wow, consumer spending sure bounced back quick." But it didn't really, did it? The US Government just injected like $3 trillion in direct payments and unemployment benefits. The consumer didn't really bounce back, the government just printed money and gave it to us. <br><br>And this week, we just learned that the national deficit is $3 trillion for the year. I did some research and the last time we had a deficit this high was in 1943 when we were fighting a world war. Over the past 20-30 years, our national debt has grown immensely, but the deficit has more or less stayed the same. All of a sudden, we're running massive deficits, like 15% of GDP. <br><br>Further, the Fed has been printing money hand over fist, keeping interest rates very low. The prime rate is something like 3.25%, and my high yield savings account is paying out 2.15%. It's never been this high before. <br><br>Lastly, I was reading about how the US Government is planning on running negative interest rates. That doesn't seem to have happened yet, but I'm sure it's in the cards. Combine all of this, and I feel like the economy is just being propped up with cheap credit and money printing. It feels completely fake. Nothing underpins the current structure except cheap money and printed cash. <br><br>And no one really seems to be talking about it. It feels like we are in a massive economic bubble, and once it pops, the damage will be unmitigated. I honestly do not understand how this hasn't happened yet. Is anyone else feeling like this? Am I just crazy?<br><br>Edit: Thanks for all the responses and insights! Keep 'em coming!
