Many people have worried that employers would dump their workers into the subsidized exchanges. Now there is good reason for states to dump Medicaid beneficiaries there at the expense of the federal taxpayer
How big could it be?…Suppose that every state takes advantage of this opportunity, and that every individual who is either on Medicaid or would be eligible for the expansion actually moves to the exchanges. The federal government would save as much as $130 billion in Medicaid in 2014, but it would be on the hook for $230 billion in new insurance subsidies. The net bottom line: a $100 billion annual expansion in federal costs.
