The buildup of debt in the US alone is staggering; Japan is staggering, everywhere is staggering. So the next time we have an economic slowdown it is going to be much worse than the last time, and if the world survives that one, the one after that is going to be worse and worse.
Because as you point out, if interest rates go higher – and they will; this current level of interest rates is not only abnormal but absurd, it has never been so low anywhere in the world – with the gigantic amount of debt we are going to have gigantic problems worldwide: more turmoil, we will probably have wars, governments fail, countries fail. This is going to be a mess.
So buy yourself a farm. Be prepared! It’s going to be a serious mess. And hopefully your farm will be far away from the marauding hordes.
