"The couple was leaving behind a wealthy existence on Manhattan’s Upper West Side, according to Brad Stone, the author of the 2013 book The Everything Store: Jeff Bezos and the Age of Amazon. “They gave up a really comfortable lifestyle and successful careers to move across the country and start something on the internet,” says Stone. “The only reason [Jeff] was able to do that is because he had an extremely supportive spouse. It was an incredible risk and one that they both took on jointly.”
"In a 2010 commencement speech he gave at Princeton, Jeff himself acknowledged the gamble his wife had taken. “I told my wife MacKenzie that I wanted to quit my job and go do this crazy thing that probably wouldn’t work since most startups don’t, and I wasn’t sure what would happen after that,” he said. “MacKenzie … told me I should go for it.” (Amazon did not immediately respond to a request for comment.)"
EDIT: @busterarm: We're not going to agree on what defines "earned", good chat.
Edit: I'm pretty sure Amazon shareholders won't agree with you about the definition of "earned" either. It's not just cash at stake here, it's voting power. Is that spousal support worth 8.5% control of the company? Up from 0%.
I'm not saying she isn't entitled to it, just that there's a difference between value through entitlement and value through work.
It's already well established fact that Jeff's/Amazon's costs in the early days were paid for with his parents' life savings.
