Hillary Clinton's net worth, $31 million is a far cry from $3.7 billion. Hillary Clinton's wealth she earned primarily from the lecture circuit. She grew up middle class and has had to earn a living. Donald Trump grew up rich and has never struggled to make ends meet like the majority of Americans. 
Clinton's platform calls for a 65 percent estate tax and wants to lower the level at which estate taxes become payable to only $3.5 million. 
By contrast, Donald Trump would eliminate the estate tax.
The political system favors the rich but the Democratic party has a history of favoring policies that increase taxation on the rich whereas the Republican party favors reducing and eliminating taxes on the rich.
