Why does the USA use a winner-takes-all style of democracy while other nations use more of a parliamentary system?
Japan and the UK both have Prime Ministers and various parties. How did the USA end up with the system we are using? Changing it would be a big hassle, but I’m curious about why it seems that modern democracies use a different system than the one founded in the 18th century.
