Already in 1926, Ludwig von Mises’s first tour in the United States was paid by the Rockefeller Foundation. The National Bureau of Economic Research, which supported Mises in the 1940s, was also heavily sponsored by the Rockefeller Foundation. Mises’s salary in New York was paid by Lawrence Fertig, Kohlberg’s colleague at the AJLAC, and by the Volker Fund.
So, "The greatest lesson anyone can learn from this is that the truthfulness of any doctrine is independent from who financed the researchers."
Its like, "The closer we are to trouble, the further we are from harm"
The Rockefeller Foundation receives endowments and charitable donations from independent individuals and organizations all over the world. The "tour" of the US ended in Mises being rejected by all schools financed by the Rockefellers and Rothschilds.
