The end of the United States will be caused by the following 3 things, in my opinion.
1. The rise of other world powers and our attempts to proudly hold onto some economic groundation while the fuckers reponsible for the depression are going to retire with their stolen riches on other cuntries that aren't boiling alive in ignorant mistakes and complacency.
2. Natural disasters which we will be completely unable to defend ourselves against.
3. World apathy for our plight.
