Something else to keep in mind is that while nearly all of our founding fathers were of the upper classes, to categorize them as being the same in their outlook would be incorrect. The American Revolution was organized and lead by the upper economic classes, those holding land and slaves (North and South). After the revolution, the real war began, and continues today. Weak central government vs. strong central government. The establishment of a central bank 'Federal Reserve' was a contentious issue. And its proponent, Alexander Hamilton, was born in Jamaica, to modest means.
TR was a great president. His vision led to the establishment of National Parks and other areas left generally unspoiled by development.
But, he was wealthy, and connected, and a politician.
