I am not so concerned about the global economy but the US is in for a massive crash in 19 or 20. The difference this time will be safety nets for people (no, I do not consider corporations to be people) have been eliminated and portrayed as evil, and Hoover techniques will be used (already began with the tariff situation) making it even worse. Hoover really screwed up with his responses to the recession which led to depression.
Just get out of debt and be prepared to relocate easily.
