Just some insight of mine...Building a crude-oil-based economy is like planning a trip....and when your buddies ditch you (when the oil runs out), all plans blow off. You could stop your plan and wait for a better timing to travel IF you could resist the leisure....
However we are all addicts and we could only keep asking/making "alternative" buddies so that the trip works. In fact even if we wanna stay, there is no home anymore coz we have burned our home. The concretes can never turn back to grasses. Wait and see things bust... If something is possible to get worse, it will get worse...that's the Murphy's Law.
