I suspect it's not widely tracked by most people, since they measure the effect of government policy by the size of their tax return. The real SHTF will happen when most folks go to get their "return" next year.
It has been happening ever since the law was passed. Haven't you been listening? Wife's witholding for medical has gone from $37 a pay period prior to enactment and signing to $415. From $74 a month to $830 a month effective Jan 1.
Folks will make the silly claim that the increase has nothing to do with oldbummercare because it didn't go into effect until this year but if you use your head for something other than to hold your ears apart you will see direct causation. Oldbummercare required benefits from insurance carriers. Price of those services is passed along to the consumer and the insurer damn sure is going to keep ahead of the costs to himself. Ain't no such thing as a free lunch. Or free medical care.
