Its a different business model that market forces should be sorting out. IF there is a disadvantage, then why should the government be the profiteer of sorting out the difference when the market would do, and is doing, that quite well. Besides, government does NOT need any new monies that they just spend on crap. They need to be shrunken down to a manageable size.
I think the argument is that the government *is* sorting out winners and losers under the current system, and this would put the government back in a "neutral" position.
That said, I don't like the bill, and would not support it unless it included substantial cuts in other taxes.
