The theory in this paper suggests that the association between economic growth and democracy is not causal as Lipset suggested. Thriving markets and economic growth do not produce democracy. Instead, both democracy and markets require the limit condition. Countries that have devised means to satisfy the limit condition can therefore sustain both democracy and the market. The two go together. Thriving markets are part of how countries get rich. To become rich, countries had to provide for the restrictions associated with economic liberty. These countries therefore have strong limits on the government and hence have strong limit conditions. Democracies with markets and economic liberty are therefore likely to be both rich and stable.
