Google - 85,050 employees (https://en.wikipedia.org/wiki/Google https://en.wikipedia.org/wiki/Google) Facebook - 25,105 employees (https://en.wikipedia.org/wiki/Facebook https://en.wikipedia.org/wiki/Facebook) Amazon has 566,000 employees (https://en.wikipedia.org/wiki/Amazon_(company) https://en.wikipedia.org/wiki/Amazon_(company)), but it's unclear how many of those are actually tech workers. Amazon has a lot of retail and warehouse workers, many of who with wages so low they qualify for food stamps. Apple - 123,000 employees (https://en.wikipedia.org/wiki/Apple_Inc. https://en.wikipedia.org/wiki/Apple_Inc.) Apple's 2014 SEC filing said that half of their employees are retail workers, so let's give Apple 62,000 tech workers. Microsoft - 124,000 employees (https://en.wikipedia.org/wiki/Microsoft https://en.wikipedia.org/wiki/Microsoft) There are around 7 million tech workers in the USA (https://www.comptia.org/about-us/newsroom/press-releases/2017/04/03/us-tech-sector-employment-approaches-seven-million https://www.comptia.org/about-us/newsroom/press-releases/201...) Even if we pretended that all 566,000 Amazon employees were actually tech workers (they're not) and the above numbers were US-only employees (they're not), that would total to about 860,000 tech workers. 860,000 / 7 million = 12.3% That means that at least 87.7% of American tech workers do not work at Google, Facebook, Amazon, Apple, or Microsoft, despite these companies being five of the richest tech companies in the world.
