CR, you look at the article I linked? Your factoids reinforce what they're saying pretty nicely. Refineries are in it for a profit- as they should be. With margins already tight, and billions of dollars in taxes and regulation- plus a hostile congress threatening to nationalize them or, at least, cut their margins even thinner, it just doesn't make much sense for them to invest in US refining.

Here's an article from the Toronto Star that almost makes you feel bad for companies like Exxon(almost). Yeah, they're still fabulously wealthy, but as it stands, the writing is on the wall for Exxon and other publicly traded oil companies. Soon they'll all be replaced by even more corrupt and greedy state-run enterprises.
