You forgot inheritance-just like your man tRump.  Also you forgot spending money in politcs and lobbying for loopholes and financial advantage like tRump did in the 1990s when he was nearly a billion in debt - and we got to bail him out too!  And all because he has so much "talent". 
How about all the infrastructure and police and resources in the US paid for by the middle class &the tax cuts for the rich have helped too. And golly gee whiz-I am being very emotional here-repealing the estate tax and tax breaks for pass through corporation for a loophole so big you could fly the shuttle through it so they don't pay fair tax and pass on all that estate money tax free. Sure, it is just hard work, ingenuity, talent, (greed, dishonesty, money laundering, advantages, despicable values and actions).  You sure don't seem to understand the mind of the "average lefty" and why would you since you are incapable of understanding anything out of your dark, narrow, uneducated perspective.
