He ain't raging. He's spitting facts. Many of the founders were the colonial establishment. Many of them heads of business, as were their backers.
They were often elected members of their colonial legislatures, and generally the most influential/well-known ones. John Adams, for example, was a member of the Massachusetts legislature for years before the Revolution. And they were all very well-read.
A large part of the Trump movement openly scorns anyone who is educated...except Trump himself, of course. And while disparaging or denigrating people because they lack a higher formal education is both wrongheaded and just plain nasty, it isn't any better to disparage people just because they
do have that level of education.
I know plenty of people who lack a higher formal education but are very knowledgeable on "academic" subjects because they are self-educated. They
read. Maybe it's history, politics, literature, science...whatever.
What I have absolutely no respect for is someone who purports to be a leader but doesn't know and doesn't care about the base level of understanding required to do the job properly.
