I believe the world economy is slow and risky but manageable. However, powerful speculators uncontrolled are going to be the problem.
All major developments be it Brexit, climate change or protectionism economy are being used as a vulnerable loophole to short the markets.
I still see is a 50:50 situation but indeed it is important to reduce debt and moving your investment to more asset oriented. This prolonged economy slow down need extreme self discipline and management to overcome and profit from it.
In short a more prudent approach is needed for both business and investment for next coming few years. The world debt just need to be fixed with damaging zero interest rate.
