The 6 billion it would cost to get to Mars could be spent somewhere else right here on Earth to help
people in need.
This Mars pipe dream is all fantasy and a big waste of money.!
A culture is defined by its highest aspirations. Exceptional advances will ultimately help the poorest and most disadvantaged also. A great many good innovations have come out of space travel. Also have others have said the energy, mineral and even water resources of our solar system could benefit us all. Militarily space cannot be ignored as command and control systems are space dependent and in the near future private space firms will develop a space capability that may be profitable also. Do we hand space to pirates and adventurers or do maintain some kind of semblance of law and order out there. If America does not get to Mars then other nations are already planning the same. The prestige that came from the Apollo missions arguably set up American supremacy for 3 decades. A Mars success may do the same. I am excited about the Orion programme but I fear that the pace is way too slow and with a little more finance and political will much more could be accomplished so much faster. America has the advantage and it is letting the accountants strangle it!
