Wow. "Not necessarily?" You have amazing faith in the probity of Hank Paulson. I know he's not a yahoo from Kentucky, but did you notice he tried to railroad through a three-page bill that prohibited any review by a court of law? Does this look like a plan intended to minimize the chance of paying subsidy prices and maximize the chance that the taxpayer will get a large return? If that were the purpose, why didn't Paulson just propose buying stock in companies, as even ultra-neoliberal economists, flabbergasted at the venality of this bill, have been urging? The whole thing is so opaque - needlessly opaque - that it only makes sense to assume the intention is to pay subsidy prices.
And by the way, even if the government makes money - a possible but doubtful proposition - that doesn't mean it's not a subsidy. Any bailout plan that succeeds will cause the prices of many assets, including financial stocks, to rise. In order to not be a subsidy, the plan has to let the taxpayer *fully* participate in that rise, not just do better than break even.
