Steve Ballmer vs. Amancio Ortega

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.

Ortega first began his career manufacturing textiles through a small family company in 1963. He owns a 10% stake in Spanish telecoms firm Telxius and 5% of publicly traded natural gas grid operator Enag's.
