Since you ask the question, you are clearly not the target audience.

As Spider Robinson has written to similar questions, some folks have another column in their life ledger, labelled 'satisfaction'. You can't see it, so their behavior seems irrational.

Furthermore, its not clear that money on Earth will have any meaning on Mars. You can't take it with you, in a way. To go to Mars at all, requires a sacrifice of your entire life on Earth, in exchange for a chance at a new life.

I would do this, sacrificing all I have on Earth, for the chance to do something really important.
