>Is that reasonable when heath-care costs, at 20% of the economy, are increasing at 10+% a year?
Yes.
One, because cash flow one way doesn't justify cash flow another way. Regardless of other costs. So I'm not sure how one relates to the other. Purchasing power and real wages don't necessarily mean you have more money to spend freely. It's a way of looking at how average workers are getting their slice of the pie, so to speak.
Two, because the fundamental reason these costs are increasing are also because of the economic system that is hoarding wealth -- the product of productivity -- into one class tier. This class tier has almost no real input or contribution to productivity and technological advancements, yet are quite literally the only ones benefiting from it.
Continuing, there is absolutely no reason for healthcare costs to have increased as much as they have. Not at current spending levels. I wish people would understand this. There is no fundamental, principle reason why healthcare costs go up except greed and the system we have chosen to implement. Price increases happen because you have private companies that have continually increased prices -- and in some cases taken drugs that used to be free and now charge thousands, if not hundreds of thousands of dollars, for products and services. A lot of which are funded directly by federal grants, and none of which the public receives returns on. Our ineffectual government (when it comes to regulatory matters) has done nothing to curtail this.

We have every ounce of data telling us "this system is wrong, it is not functioning by any metric" Yet a large portion of the populace doesn't care or continues to adhere to the mantra. It's not religious, it's an economic cult sprinkled with political astrology. Capitalism has its place. But it needs to be put back in its place, so to speak.
