More than six years have elapsed since 'something' happened in the world economy - but what it was, and what its significance was, I am less clear than I supposedly was then - Now I don't believe anybody at all knows (even if plenty think they know), and I don't really trust anybody on the inside to tell me even of what they do know!
What I personally know, from observation and experience, is that nothing useful at all has been learned from 2008.
Or if it has been learned, then it has not been acted-upon. Because absolutely nothing constructive has been done - and many, many anti-economic, anti-productive things have instead been done; and therefore I am sure that economically things now are in reality much worse than they were in 2008.
What I strongly suspect is that politicians in the West have learned multiple ways of invisibly inflating the currency and covertly stealing from the savings of their productive populace - by combinations of borrowing, printing money, and stealth taxes.
And this wholesale secret theft is incrementally increasing year on year to subsidise what are clearly massive (multi-million) expansions in the numbers of barely-productive and non-productive population who have luxurious standards of living; and in general to create a facade of fake prosperity based on confiscation/ borrowing-fuelled bribery, corruption and subsidy.
