Hi Tom,
I don't know whether to be scared by this article or consider it a contrarian sign of good times to come. If higher interest rates and inflation are the only way out of our 'debt bubble', now is not a good time to be debt free, it's a time to have a lot of long term fixed rate debt invested in assets that are likely to appreciate with inflation.
The world economy is so complex that I'm not sure anyone can really understand it. I have a record level of cash, for me, so I think I'm relatively well prepared for whatever is to come. I'm not sure armageddon is coming, it's been predicted a number of times before. If this situation was so obvious, why are long term bond yields below 5%?
