Been a member of both. The “rich”, which is laughable, and the working class.
As a member of the former, I can tell you that a damn big portion of money went back into the business. Not only through paying my employees and hiring new ones, but buying and investing in other things (thus growing other businesses) to grow a business.
As a member of the latter (middle class worker), I hated the former, until I worked my way up and introduced myself to the former. 😉
And no, I personally am not rich, but I owned a business and our numbers would make one think we were.
