Jefferson warned about big cities:
"When we get piled upon one another in large cities, as in Europe, we shall become as corrupt as Europe".
His vision was a nation of farmers, ranchers, and cottage industry..small business.
He also said:
"I believe that banking institutions are more dangerous to our liberties than standing armies. If the American people ever allow private banks to control the issue of their currency (Fed Reserve), first by inflation, then by deflation, the banks and corporations that grow up around the banks will deprive the people of all property until their children wake-up homeless on the continent their fathers conquered."
Wise man, saw it coming.
