Free market economies work well when there are intelligent, informed consumers and competition. Corporate monopoly-based economies work well for the corporations. Consumers/customers must purchase needed goods and services and if there is only one source available, the right to vote has been lost. Corporate monopolies exist because we allow them to exist and they have power because we give it to them. We can support our free market economy and assure its existence by supporting competition and voting for politicians that have a track record of doing the same. Would you expect a politician who has support from the petroleum industry and family interests in petroleum, to act in the petroleum industries best interest? Would you expect them to support your interests by actively developing alternative fuels and not going to war to facilitate petroleum fuel monopolies?
