"If our own great grandchildren don't have lives better than ours, something has gone very wrong". (The foundation was formed from the merger of two smaller, pre-existing efforts: the William H. Gates Foundation and the Gates Learning Foundation.) The organization, which is focused on global health and education, has distributed $46 billion to grant recipients through past year.
He has given $1.5 billion to Blue Origin, his company developing technology for space travel.
Bezos said the schools would "use the same set of principles that have driven Amazon" and that "the child will be the customer".
The first will fund existing nonprofits and issue annual awards to organisations doing "compassionate, needle-moving work" to shelter and support the immediate needs of young families.
Many on Twitter, however, did not hurry to heap praise on Bezos' new endeavor, pointing out Amazon's practices of underpaying its workers and forcing employees to work in stuffy warehouses without air conditioning. "What the president should say is, 'This is right, I'm glad I'm being scrutinised.' That would be so secure and confident". Go Gold boxes by Amazon are uniquely-designed packing boxes that feature a gold ribbon - the worldwide symbol of childhood cancer.
There will also be full scholarships for Montessori-inspired preschools in "underserved" communities, he said.
Asked about Trump's repeated criticism of both The Washington Post and Amazon, Bezos called it a "mistake" for any elected official to "attack media and journalists".
But he paraphrased Washington Post editor Martin Baron as saying that "the adminstration may be at war with us, but we are not at war with the administration".
We will build an organization to directly operate these preschools. "Most important of those will be genuine, intense customer obsession".
"The Bezos Family Foundation - and Jeff obviously has a role in that - has been engaged with early learning initiatives for years now", Burgess said, adding that it could only help the political momentum toward universal pre-K, as Seattle's preschool program is also once again on the ballot in November. Bezos calls the endeavor a blend of business and charitable work and hopes that one day we can move industrial activities off Earth, preserving it as a place to live and do less harmful activities.
Many Twitter users agreed with that reasoning. "If billionaires like Bezos were properly taxed then we wouldn't need billionaires like Bezos to sweep in and "rescue" people failed by our underfunded systems," one wrote.
