US healthcare is expensive, and 1 in 6 Americans can’t afford to use it; but that proportion is down significantly since 2008. The two biggest effects are the number of Americans with healthcare insurance since the implementation of the Affordable Care Act (Obamacare), and the improved economy for some portions of the population. The poorest continue to have problems, but enough others are benefiting that the general trend is positive. An indirect cause could be the drop in fuel prices that made it easier to shift funds to healthcare from transportation and heating. Good news about healthcare. Surprised?
