We should not conflate political theory and economic theory. Even though both are necessary, they should be kept separate. Political theory relates to the form and structure of a government and the means by which political power is exercized. In a democracy, the form and structure of government is that of "a people" governing themselves viz. a government "of the people", "by the people", and "for the people". Of course, "the people" need housing, work, food, clothing, etc. to subsist on a day to day basis. Both these needs are provided by the form of the social and that of the economy. Its at this point where the two disciplines can be easily conflated. Politics relates to governing by means of the Constitutional form and structure of government. The economy and capitalism relates to the circulation of money in such manner that the economic and social institutions are made more and more productive and efficient. The economy can evolve and become more 'modernistic', but government is stable and is not subject to evolution like other social and economic institutions. If government 'changes'it must be towards better democracy.It cannot change form, it can only improve the structure by which it implements its democratic form. Democracy is forever. An economy needs a medium of exchange that circulates among the busineses and the people,viz.money. Of course, all the people and the busineses are at the bottom of triadic government( Constitutional Government). Hence, circulation has to be kept at the bottom. If the money stays at the top, it will not circulate at the bottom.If thats the case, there will not be sufficient circulation to keep the social institutions viable. Work will break down, wages will break down, and so will home ownership, medical care, and social security, etc.. As important as money is in our social and our economy, it cannot serve as a political value. Political principles are the engines of a democracy. Money cannot and should not drive democracy. The constitution and a political theory that conforms to the principles of a democracy are the sole criteria for political theory. Human history has not come to the end and it never will, nor will the need for government, nor will the need of an economy. Todays' democracy, todays' economy, and todays life, will be tommorrows, next months, and next years history. Capitalism should feed the people, not rule; capitalism is not government. Capitalism is driven by the profit motive and, unfortunately, greed. Democracy is driven "by the people" and more importantly, "for the people". Capitalism needs democracy; democracy does not need capitalism. Lets keep both of them, but lets keep them separate.
