noblesse oblige 

Literally means, "nobility obliges". It's generally used to imply that with wealth, power, and prestige come social responsibility. It's mostly used to refer to the wealthy who are condescending and shower their money and privileges upon those who don't necessarily want it.

Our landlord gave us a basket of fruit for Christmas, as his noblesse oblige.

noblessez-faire

someone elected to government noble enough to avoid cronyism, and allow citizens to prosper

(portmanteau combining these French terms, used in English):
1. Noblesse oblige: Whoever claims to be noble must conduct himself nobly.

2. Laissez-faire: transactions between private parties free from state-intervention --------> 3. (my neologism)

People running for office -- as wealthy as Ross Perot, Mitt Romney, and John Kerry -- would ideally be uninfluenced by lobbyists' money, level the playing field by the principle of "noblessez-faire".
