Good morning, RSIR Nation! I'm curious to see if history will repeat itself. A century ago, America rolled into one of the most transformative eras of economic growth and lifestyle pursuits with the first world war over, a booming stock market, integration of consumer debt products (leverage) and new innovations. This was the birthplace of many personal liberties, good times and prosperity. A lot of the convenience was brought by the mechanical devices that made life better. American cities flourished.
