Obama's dad was a high mucky muck in the Kenya government, his mum was a doctor, his stepdad a oil executive, his grandma was the most powerful banktress in the Pacific Rim.
He came from money.
But you're right he earned his own fortune in the field of Public Service, serving in political office. Although in reality, it sounds like Emoluments to me. Trump made his money in the private sector
But gee, don't 'Community organizers' get paid millions?
Michael Obama made over $250K a year as some sort of 'public relations vp' at Cook County hospital, after all; Daddy was a precinct captain it seems. Sounds like a do nothing job to most of us, same as Obama's mysterious 'resume'.
