Here's how money can be made:
"Bonds are subject to interest rate risk. Interest rates and bond prices are inversely correlated. When one goes up, the other goes down. This may not matter if an investor buys and holds a bond to maturity. In this case, it would collect the scheduled coupon payments and receive the face value when the bond is repaid."
Bold is why they will crash. Nobody will have the confidence to hold long term debt because socialism and governments are collapsing. The people are rising up against the establishment and status quo corrupt politicians who tax them to death.
