What taxes are going to be raised to pay for the radical increase in spending? What's the next industry to be demonized and have punitive penalties, taxation, or nationalization applied to it? Is somebody else going to be shaken down the way BP Oil was even when there was no legal authority to do it [1]? What other radical changes to the economy are going to be proposed if the recovery continues to be anemic, and how many dollars are going to be vacuumed out of the private economy to accomplish these changes? How much more loan disasters have been hidden, and how will the administration react, and how many dollars will be vacuumed out of the private economy to implement the reactions? How will the government react to the oncoming pension crises, and how many dollars will be vacuumed out of the private economy to do it? By what order of magnitude will the Obama health care bill's costs be underestimated[2]?

It doesn't even matter whether these are true; I'm not really trying to argue these points or I'd back them up better, I'm just answering your question. (So, for instance, replying to me to argue about the legal authority for the BP Oil escrow account would be missing the point.) It only matters that enough people in business think they are true. It doesn't matter whether they are entirely correct, it only matters that the concerns are correct enough. Somewhat loaded terms were chosen deliberately to give a more accurate impression of how these people are thinking.

[2]: I don't even mean this as an attack specifically on that bill; observing that governments almost without exception underestimate costs is merely realism, not politics, and when you're talking about something the size of the health care bill, being 50% off is a big deal.
