This guy's worth hearing[1], imo. He seems to concur with George Soros, to some extent. AISI, in the UK we have near record high private debt of £1.5 trillion. Don't know the ratio to GDP, it's likely not good, and if we have a slow down it can only get worse. It's pretty much the same for the US, I think. I don't think the world economy is going to recover any time soon. It's probably best to get used to it flat lining.  Spend more time relaxing with a pint of real ale or whatever it is you enjoy doing.
