>The elites were always voracious readers

Since when? All the elites I know spend their time taking expensive vacations and doing too much drugs.

Those are not elites but wealthy, if completely irrelevant people.

Elites would be powerful politicians, advisors, or big-scale investors that pull actual strings. And these people are pretty universally voracious readers.
