Money, money, money! One day suppose all oil/gas, mining and corporate controlled resources could become unaccessable due to massive earthquake, foreign attack on us or nuclear bomb explosions in Europe that would lead to the total collaspe of Wall Street. Decades to recover if ever. That would be interesting to see how people would react or survive today. Riots all over due to rage, fear and hunger? No jobs, no unemployment, welfare, pension retirements, Social Security? In 1929 crash, America still had more farmers and rural than now. So food was still available if you gleaned the fields. Also faith in government.  Now? We have no faith,  farms of ethenol cornfields, Monsanto GMO growing fake food with no nutrient value and water is polluded and toxic in many places. Food, clean bottled water and medicine controlled by one entity. Horror movie? Reality.  Sooner or later.
