When interest rates are 0%, any amount of growth compounded over years is attractive. When you can get a 5% risk-free return from treasuries, even 7% rate of return is unattractive when compared to the safest asset on earth returning 5%. My point is, layoffs will continue until companies are much more efficient, or interest rates go down.
I got news for you. The riskiest place to park your money right now is government bonds. Long-dated US treasuries are risky. You will end up losing everything.
But if you insist on US treasuries, be my guest. I need someone to trade against.
