It is unfortunate that Climate Change is one of those controversial issues in the US, and the world in general, which frames the argument in moral terms.  The other issues that come to mind are Gay Marriage, Abortion, and Immigration Reform.  Moral issues unfortunately are difficult to decipher, and many political theorists would agree, belong outside of the realm of political discourse.   Thousands of years of history tells us that when issues are framed as moral imperatives, the issue never gets settled.  Just think back to the protestant reformation, for starters.  Or the moral issues raised by the idea the earth revolves around the sun, rather than the inverse arrangement.

To my fellow students:

The economic depression is likely to last for some time without the opening of some new economic frontier for further exploitation.  Indeed, after this financial crisis it seems the last 15 years have been more economic redistribution rather than economic growth.  Do not get me wrong, I am not innocent of going after some of that redistribution.  And I would likely continue chasing after personal economic prosperity, even after having thought through the consequences of taking the post-ivy league path of corporate economic security, and having borne it for some short time in, because I, like every individual educated in the economic orthodoxy, believes in the power -- no sovereignty -- of free markets.
