Interesting that you brought up natural selection, since arguably countries do have some sort of natural selection, but it's fairly limited since they are restricted to some geographic area limiting the competition to neighbouring countries (at least until recently).
However the same restriction don't apply to corporations, and indeed those are heavily competing over their means of existence (money). Which gives an interesting perspective to the current tendency of large corporations to improve their own chances of survival by dodging taxes, influencing politics etc. In some sense it does seem like corporations have become 'intelligent' and are attempting to change their environment to suit them. I'm not too sure what the end result will be, but I fear it's unlikely to be beneficial to humans.
To stop this we may have to, as you say, kill "God".
