"Most tax credits drop straight to the bottom line – it’s why companies like Enron considered its tax compliance section a “profit center”. A few hundred billion dollars of tax expenditures is a major carrot to offer. Surely, a modest hike in income taxes for people who make more than $400k in income and stupid enough not to take that money in capital gain would be worth trading off for the few hundred billion dollars in corporate pork. This is what the fiscal cliff is about – who gets the money. And by leaving out the corporate sector, nearly anyone who talks about this debate is leaving out a key negotiating partner."
