Practically nothing we as individuals would be able to do would really result in much change with respect to any of this, so aiming for that is rather pointless any way you go about it. But at least by coming to places like this you are heard on some level. It's at least more than essentially doing nothing or what effectively amounts to nothing (voting with your wallet).
Come on C DM, this really is a pessimistic view... If everyone thinks this way, then how will things ever change... Are we supposed to put up with status quo?
