It is argued that the coexistence of modern capitalism and democracy was the result of the creation of the modern welfare state that allowed for a relatively stable political atmosphere and widespread support for capitalism during the Golden Age of Capitalism in the post-war era.
The United States is often seen as having democratic capitalism as its political-economic system although some argue it has become more authoritarian in recent decades.
The ideology of "democratic capitalism" is one that has been in existence since medieval times. It is based firmly on the principles of liberalism which include liberty and equality. Some of its earliest promoters include many of the American founding fathers and subsequent Jeffersonians.
