All this expense to collect few martian rocks ... The money will be much better spent on making planet earth a better place.

Wrong; this is an effort to permanently live, to colonize Mars. on the counts of water: wrong there is lots of water on Mars; air can be made from the regolith; temperatures are much warmer down in Valles Marineris during summer, daytime temperatures may reach highs of about 70F.
Spending money to make Earth a better place according to whom and which version? And when a more than a mile diameter rock hits, will that make Earth a better place too, since it will be an ELE event?
I have heart many stupid ideas. Living on Mars takes the cake.
