Steve Ballmer vs. Michael Bloomberg

Ballmer and Microsoft cofounder Bill Gates were classmates at Harvard. Ballmer created a website called USAFacts.org for people to look up and understand where the government is spending money.

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.
