The official methods for determining the health of an economy are based primarily on the interests of the wealthy.
They tell you that a high GDP and the strength of the stock market are the best indicators of a good economy, but these two things have almost nothing to do with real economic health, rather they relate instead to the profitability of corporations and the security of the wealth of the rich.
Employment at livable wages, affordability of food, housing, and other necessities, the stability of the currency, a large middle class, a low level of disparity between rich and poor, a minimum level of indebtedness (personal, corporate and national), equitable taxation policies, and so on, are more reasonable measures of economic health.
