EDIT: just looked it up and most of "industry weeks"'s Top 50 manufacturing companies seem to have profit margins in the 10% range: http://www.industryweek.com/resources/iw50best/2015/48
This is not "stay small".
Its something more disgusting that comes with success... you want more success.
Its the same with athletes like Tom Brady that could easily retire but don't. They keep playing because they like the challenge and they like to win... not the paycheck.
An example of money granting power would be Donald Trump. Do you really think Trump would be where he is politically if he wasnt wealthy?
An example of power opening doors to money is Barack Obama. He and Michelle were nowhere near wealthy 10 years ago. Now, after several book deals, speaking engagements, and much more, they are financially in a financial position that many Americans would consider to be wealthy - albeit nowhere near Donald Trump level.
