Why would it? It has less usable resources than loads of places on Earth that aren't used at all.

Maybe if Mars is some sort of lawless territory it can become the libertarian haven some rich people want, and could trick some future slaves to get sent over there....

It still has enough available resources (that we know of) to do well. And getting people to emigrate won't be an issue at all. Think of it like nuclear technology; developing an atomic bomb isn't difficult at all since the physics has been done 70+ years ago. Now it's just a matter of engineering. Same with building up an infrastructure on Mars. Somethings like large foundries probably won't need to be replicated, since 3d printing will probably suffice, but off the top of my head, I can't think of any technology that is out of reach.
