Sure, but our systems of capitalism (as I showed above) promote and create reward systems for "shortsightedness". We are but products of our environments and our systems... So, we can pinpoint (bad apples) and blame their individual greed as the problem (it's not) or we can blame the system that rewards greed, rewards self-serving behavour and 'short-sightedness'. First step to fixing a problem is admitting we have one.
