I think we will have to have everything fall apart again in order for things to change. The main problem is the fix for our last depression was war. That won't work anymore, luckily we actually do have the agricultural and industrial means in place and running to sustain ourselves, after a crash these will have to be bolstered and foreign policy changed. Exporting high and importing only what is needed to maintain good foreign relations. MOST IMPORTANTLY- A depression will hopefully force the poor and middle class to stop and take a look and educate themselves. When the poor get more educated on how they work and affect others lives all over the world- We may see a shift, that is key.
