Why the World Economy will collapse within the next 3 years

Hi all

Thousands of articles, books, posts, etc. have been published in favor or against the next financial/economic crash after 2008. Nobody can foresee the future, of course me neither. Nevertheless, I believe that our world economy at least will considerable decline (or even worse, collapse) - here is why in a nutshell (w/o going into details):

1. Nearly all countries (corporations and private sector as well) of the world have huge debt accumulated (e.g. UK more than 500% of GDP) - with an accelerated speed within the last years
2. Nearly all central banks of the world have enormously expanded the amount of money supply (aka as "Quantitative Easing") - also with an accelerated speed within the last years
3. The growth rate of the world economy is comparatively very low compared to the rates of point 1. and 2.
4. The wealth gap between the richest and the poorest within most of the so called developed world is increasing more and more - meaning the social problems are increasing
5. The governments of most countries tend to become more radical (to the left or to the right) - meaning increasing tensions between neighbor countries

Put together, these facts mean a very unhealthy and not sustainable trend. Since real changes (better: reversions) for these points would need at least 4-5 years, I believe that there will be a big crash within the next 3 years.
