Late Stage Capitalism

You know if I hadn't gone to real, actual college for politics and economics I might be swayed by your... argument style. For example you clearly don't know the first stock exchange had stock only for the Dutch East India Company. So named because they were chartered by the Dutch Government. They were also one of the earliest Joint Stock Companies. And the time periods of Renaissance and Early Modern Era certainly aren't in dispute.

You should also know that David Hume's writings are available online. Funny thing is, as far as I can tell he didn't use the word capitalism once. It's kind of hard to write additions to an existing ideology without using it's name. In fact Capitalism as a name is given in 1850, by Socialists who are attacking the system. Going back to Adam Smith and David Hume is because they were writing about changing the economic system, and their writings were largely adopted.

About ideologies needing popular approval, that's kind of how that works. As much as they might wish it, philosophers cannot make an ideology a popular movement on a whim. And yeah, the wiki page cites a book review by The Economist, which talks about banking in Florence. and if Banking is it then we, again, have to go back to ancient Mesopotamia, and Capitalism has no definition because it always was and always will be. Don't trust Wikipedia, just don't. You're always going to find some horrible stuff in the sources.

I said before that elements of Capitalism existed before the main ideology of it. Like any other ideology; economic, political, or personal, it stands on the shoulders of the systems that came before it.
