When the elite seek to rub elbows, many head to private clubs where they can socialize with other wealthy types behind closed doors. Like New York's CORE: club, which caters to "powerful business leaders and influential visionaries." It not only offers dining, a gym, a spa and concierge services, but members also enjoy cultural programming and social events hosted by celebrities.

Membership can be yours for only $50,000, plus annual fees of $15,000, ensuring that club members are 1%ers only.
