With most peoples property, business's, and corporations having loans or being mortgaged many people say the banks already do own most of this country. So in a sense the fear of the rich buying up this country has already happened, and it happened in this non-Libertarian system through legislation.
Thomas Jefferson
"If the American people ever allow private banks to control the issue of their money, first by inflation and then by deflation, the banks and corporations that will grow up around them (around the banks), will deprive the people of their property until their children will wake up homeless on the continent their fathers conquered."
