Michael Bloomberg vs. Larry Ellison

In 2018, Bloomberg pledged $1.8 billion to Johns Hopkins University, his undergraduate alma mater, adding $1.5 billion he had already given the school. As a teenager, Bloomberg worked at an electronics company in Cambridge, Massachusetts.

Ellison never finished college. He started out building databases for the CIA. Daughter Megan has financed films such as Zero Dark Thirty and American Hustle; son David produced mainstream movies like The Terminator and Mission: Impossible".
