The Rothschilds and the Rockefellers run the banking systems of the world.
The Rothschilds
"The few who understand the system, will either be so interested from it's profits or so dependant on it's favors, that there will be no opposition from that class." — Rothschild Brothers of London, 1863
"Give me control of a nation's money and I care not who makes it's laws" — Mayer Amschel Bauer Rothschild
