Subsidies in ObamaCare’s government-run insurance exchanges would dwarf tax-breaks for employer-provided insurance, with many families in the exchanges getting $10,000 more in subsidized coverage than families of identical size and income with employer-provided insurance would get in tax breaks.  This would likely lead to far more people finding ways to jump to the exchanges than the Congressional Budget Office has forecast — which in turn would raise ObamaCare’s costs far beyond official projections.
