The orginal economic community arose in Europe (mainly Great Britain) with the SuperordinateGoal of the Capitalist Revolution (this is not a Marxist argument...just a good term for that historical period). An EconomicCommunity is a community of individuals who come together to more effectively provide goods and services to individuals and communities, for the benefit of the consumers (lower prices), and the EconomicCommunity (in terms of profitability, financial stability and ability to expand it's production capability)
