Really, no one knows how the SHTF scenario will play out. Yes, it could be sudden with a war, financial collapse, or civil war. But, it could also play out very slowly as it did in Eastern Europe after WW2.
Back then, before and shortly after the war, most of the businesses providing staples such as food, clothing, and to a lesser extent, energy, were small business concerns. Large corporations were not the mainstay. However, communists governments came in and nationalized and consolidated all aspects of large industries autos, steel, coal, food. Small business died because they lost market share and were taxed out of existence. As small business died, competition decreased, and the communist East bloc nations become progressively poorer. Innovation and advances in technology apparently could not take root, and economic progress was not possible. The whole society, save the elites, became progressively poorer.
Obama’s model appears to be directed at destroying small business and essentially nationalizing large corporations. As in Eastern Europe, we too may see a slow draining away of wealth, over decades, until a critical collapse occurs.
