Yet another negative for the Unaffordable Crap Care Act. The limitation of $2500 effectively makes any amount over that 25%+ more expensive. My guess is that this was done to increase tax revenues to aid in paying for this chunk of crap, though it was probably sold under some other guise… like “nobody should need more than that.” I wouldn’t bet on it.
