Came across this tidbit recently:
(Haven’t tried to verify its accuracy..just passing it along, since there was recently a debate among some Austrians and their detractors about whether the Rothschild controlled the gold market)

The Missionary Review of the World, Volume 29, printed in 1906 disclosed:

“The Possession of Wealth: One Jewish banking house is estimated to control $30,000,000,000. The Rothschilds in ten years loaned $482,000,000. Nearly one-half of the gold coined, of the entire world, is said to be in Jewish hands.”

How they figured that out is a bit mystifying, but there it is.

And more on the Rothschilds:

Dutch economist Ad Broere, in his 2010 book “Ending The Global Casino,” informs us that,

“The 19th century became known as the age of the Rothschilds when it was estimated they controlled half of the world’s wealth. While their wealth continues to increase today, they have managed to blend into the background, giving an impression that their power has waned. They only apply the Rothschild name to a small fraction of the companies they actually control.”
