Do most people join politics mainly for serving people or for other reasons?

Question

Answer 1

Pretty self evident. 
I'll answer with a couple questions.  How is it that so many in politics in Washington are lawyers?
Lastly, how is it that so many of them come to Washington with more modest incomes and leave or continue serving as millionaires?

Connect the dots....

Answer 2

Two principal reasons, for nearly all politicians.

1. Money

2. Power

Not necessarily in that order.
