The man you paraphrase, Upton Sinclair (He said, "It is difficult to get a man to understand something, when his salary depends upon his not understanding it!")

The man you paraphrase, Upton Sinclair (He said, "It is difficult to get a man to understand something, when his salary depends upon his not understanding it!"), was a socialist and would probably retort that it is your salary, your luck and privileged position, that prevents you from understanding. UPDATE: I did a little digging, and the quote is from I, Candidate for Governor and How I Got Licked, a book whose motivation was to grow support for Sinclair's End Poverty plan, which started out as his End Poverty in California Plan, the core of his platform when he ran for governor.
