Revenue != Income. Gross profit (before paying any taxes) will probably be a fairly small percentage of turnover in manufacturing - you have to pay employees, purchase supplies, etc...
Being someone who owns a company with no investors that makes money (ie sort of a cash cow) I can say its not that you want more money....
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.
Power does not only come from money, though (but is obviously a part of it). Having, say, $50m in the bank does not by default give you power. In most cases, you will still need to run in certain circles and be accepted by certain people.
Its a chicken and egg scenario. Money confers a certain level of power. Power, however, does open doors to opportunities to make money.
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.
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
