I used to think Nuclear Family ties,bond and urge to meet your immediate family's need and leaving fortune for your children is the greatest motivation that pushes people far in career, business and chosen endeavours.
How on earth where this guys able to get all necessary education ( sometimes more than required),career success,and political elevation knowing they had no child or children to celebrate their success or victories with.
What motivated them through out those hard times on their way to the highest political seat in America and being the Most powerful Man in the world?
Kamala Harris is highly educated,she was an Attorney General of California 2011-2017
She was a Senator 2017-2021
Vice president 2021-2025
She is now the Democratic Party Nominee,and might become the next president of the United States of America.
What motivated her through out all her years of education and career and personal struggles? Could it be reproductive issues, Hyper Feminism or just plain disregard for concept of family values?

Concerning Empathy, she's been accused among the black community for putting a lot of black people away,I mean sending them to prison as an attorney,for crimes as petty as weed possession.
