Mandates are cool! Now, given the choice of all the possible mandates (go to mars, fix the environment, fix politics, cure some type(s) of cancer, address aging, fix food distribution, etc.) can you show your work behind why the mandate of going to mars would be the best? Surely fixing politics, for example, would have a multiplying effect on the efficiency of everything else we do and would just accidentally bring up the living standards of millions of people.
