Starting over on a new planet will reset everything you think you know about economics.  The utility of your wealth on Earth is of no practical value to people on Mars unless there is a way to transfer that wealth into things you actually need on Mars to survive, and we're probably hundreds of years out from having cross-planet commerce after we establish a colony, assuming we even will.  Money will have no practical value on Mars because there is no excess anything to spend money on.  Every ounce of effort of the settlers will be devoted to survival.  An economy can only develop when there is voluntary excess savings from what you create past what you need to survive, and that's not likely to happen for hundreds of years.
