PROBLEM: These American billionaires also share a few quirks: Microsoft founder Bill Gates  Facebook CEO Mark Zuckerberg   Oracle founder Larry Ellison  dropped out of college. Jeff Bezos  Larry Page and Sergey Brin all went to Montessori schools  where children are encouraged to think independently and creatively rather than following traditional rules. It seems  too  that billionaires really like houses in Hawaii.
As is the case with the richest women in America  the richest people in America donate a lot of money to causes they care about. Some of the men on this list have donated hundreds of millions into research designed to improve human lifespan and eradicate dangerous diseases  such as Alzheimerâs disease and cancer. Warren Buffett  Gates  Zuckerberg  and  Ellison  have gone a step further and promised to give their fortunes away as part of The Giving Pledge  an initiative designed by Buffett and Gates to encourage billionaires to funnel their vast wealth to philanthropy.

 Ellison   73 â another college dropout â co-founded the software firm Oracle in 1977. In addition to owning about 25% of the company  he also owns the entire Hawaiian island of Lanai  a sailing team and even an entire tennis tournament  the New York Times reports.
While known for living large (the billionaire owns a 288-foot yatch)   Ellison  started out with modest ambitions.  His  parents  who adopted  him  when  he  was nine months old  wanted  him  to be a doctor  but  he  left school when  he  realized medicine didnât interest  him .  He  moved to California and worked as a computer programmer and a rock-climbing instructor and river guide  according to the Times. At this point   Ellison  said  he  was âpretty happy with  his  life.â
But after a series of jobs   he  became part of a company working to establish a new type of software database. That company would become Oracle  now one of the largest software companies in the world.
 Ellison   like other titans on this list  is interested in extending human lifespan  and has given over $330 million for research into aging and related diseases.
Four-times divorced   Ellison  has two adult children and calls  his  $70 million Woodside  Calif. estate home. However   Ellison âs massive real estate portfolio means  he  never spends much time in one place.  He  owns additional properties in Japan  San Francisco  Malibu  Lake Tahoe and Rhode Island.

SOLUTION: Larry Ellison

PROBLEM: CAIRO (Reuters) - To Hisham Genena  the assault appeared well-timed. Egypt’s former anti-graft chief was on his way to appeal against the disqualification of President Abdel Fattah al-Sisi’s strongest potential challenger in an upcoming presidential vote.
 Sisi ’s office referred questions to the electoral commission.
 Sisi  faces a single opponent in the election who has said  he  supports the president.
In a speech announcing  his  candidacy last month   Sisi  said: “I promise you that the next presidential elections will be a model for freedom and transparency  and that there will be an equal opportunity for all candidates.”

SOLUTION: Abdel Fattah al-Sisi

PROBLEM: Six years ago  the contested story of Sen. Elizabeth Warren's Native American heritage began its rise from local newspapers to national headlines  and eventually into presidential speeches and Twitter feeds.
On Wednesday   Warren  raised the subject  herself  — not budging from the story  she  has relayed for years — in a surprise speech to the National Congress of American Indians.
And I want to make something clear. I respect that distinction. I understand that tribal membership is determined by tribes — and only by tribes. I never used my family tree to get a break or get ahead. I never used it to advance my career ”  Warren  said.
The stories  she  grew up with are real   Warren  said  which is what  she  has regularly said on the matter. There is no known documentation of  Warren ’s Native American ancestry (though somewhere in the 2012 back-and-forth a genealogist estimated  Warren  was 1/32 Cherokee)  but the senator has steadfastly argued that she was raised on stories of Native American family members and this is what she knows to be her family's heritage.
 Warren  has been adamant about the pride  she  feels to be Native American — though the topic has dogged  her  politically. At the event  a days-long policy summit in Washington  D.C.  attended by a wide range of tribal leaders   Warren  described  her  dedication to fight against the “country’s disrespect of Native people.”
“For far too long  your story has been pushed aside  to be trotted out only in cartoons and commercials ”  she  said.
 Warren  used President Donald Trump’s nickname for  her   Pocahontas  as an example of the disrespect.
The questions began  however  four years earlier. At the time  the Republican incumbent senator of Massachusetts  Scott Brown  was up against  Warren  for the senate seat. He brought up  Warren ’s undocumented claim of Native American heritage in a debate and asserted that she’d been using it to get ahead in jobs.
The main evidence of  Warren ’s use of  her  heritage was to list  herself  as a minority in a legal directory in the 1980s and 90s.  She  was later described as the only minority female faculty member at Harvard Law School in a 1996 survey report on diversity.
 Warren  has repeatedly denied that  she  ever used it to advance  her  career. “All I can say is  I busted my tail as a teacher. I am qualified for my job "  she  said in 2012.
On  her  family   Warren  said  “They’re gone  but the love they shared  the struggles they endured  the family they built  and the story they lived will always be a part of me. And no one — not even the president of the United States — will ever take that part of me away.”

SOLUTION:
Elizabeth Warren
