Peter Krämer is a Hamburg-based shipping mogul from Germany. His estimated net worth is $10 billion. In 2012, he became an infamous personality after he was a vocal opponent of Bill Gate’s Billionaire’s Pledge, where billionaires would donate a significant percentage of their net worth to charity. According to him, the effort is a way of showing “a bad transfer of power from the state to billionaires”. He spoke out for higher taxes on billionaires instead, so they could not avoid paying taxes through their donations. Krämer donated millions of euros in 2005 to “Schools for Africa,” a program operated by UNICEF.
