Or better put, does the financial status of ones family background, that is, does one being born and brought up by rich or poor parents, have a lot to do with how well they do later in life when they attain leadership roles in big corporations and businesses or become the president of a country?
I don’t think your parents’ financial status has anything to do with how well you perform in your vocation; it’s all on character, and whether you have poor or rich parents, they can nurture you to become a good leader.
No class of family has a monopoly on raising a child with great character to become a leader or CEO in a big company or country.
There are great CEOs who started poor but rose to the top of a big company. It's how your parents raised you, and financial status is not the only factor.
