At the start of the Industrial Revolution in the late 18th century, entrepreneurs seeking wealth started profit-generating endeavors using two new tools: corporations and equity. Capital was scarce, so, as with any rare good, to accumulate it conferred a great deal of power, access, and status. Several generations of entrepreneurs began amassing capital by creating businesses, with value captured by equity. The family names of many of these titans of industry have made it into modern parlance as synonyms of wealth and status—Rockefeller, Carnegie, Vanderbilt.
