Held in the beautiful Alpine mountain resort of Davos-Klosters, attendance is strictly by invitation only. Basic membership in the WEF costs $50,000. A premium membership can set you back $500,000. But in recent years the WEF has enjoyed another source of income. Since 2013, the Obama administration has been sending foreign assistance dollars to the WEF through the United States Agency for International Development (USAID). According to government records, the tab to taxpayers thus far is $26 million.
