be rolling in wealth

To be extremely rich; to enjoy the benefits or luxuries of great wealth. The corrupt politicians and businessmen of this country are rolling in wealth while the greater majority struggle to feed our families. It is time we took action! My girlfriend's family has been rolling in wealth for years. I don't know what I can offer her that she doesn't have already! These companies are all rolling in wealth, so they can afford the very best legal teams in the world. What hope does an ordinary guy like me have against them in a court of law?
