Imagine what you would say if they actually did so: invest (more than) a few billions in making part of Mars habitable by, say, building one of those 50's SF domes or something outlandish like that. Move there with their billions locked up in the new colony. Make it work, prove it actually was feasible. Manage to stay alive long enough to make the colony largely self-sustaining. Never mind the how, never mind the likeliness of it happening, just be John Lennon for a second and Imagine.

Those fat cats took their billions to create their own colony on planet X while we're left here on a dying Earth

Why should those greedy capitalists get their own planet? They should open it up to refugees from Earth!

Mars wasn't built by Musk & Co., it was built by $(insert_favourite_group) and belongs to them

Etcetera. Same old story, same old song. Quite a tiring one at that. I'd say let them have a go at creating a Mars colony and if they succeed - which is rather unlikely - they get to decide what to do with their settlement.
