Inequality Is a Choice

From the site:

Starting in the 18th century, the industrial revolution produced giant wealth for Europe and North America. Of course, inequality within these countries was appalling — think of the textile mills of Liverpool and Manchester, England, in the 1820s, and the tenements of the Lower East Side of Manhattan and the South Side of Chicago in the 1890s — but the gap between the rich and the rest, as a global phenomenon, widened even more, right up through about World War II. To this day, inequality between countries is far greater than inequality within countries.
