Why isn't the escalating drug shortage making more news?

According to an article in Daily Finance some common causes for the shortages include manufacturing difficulties, natural disasters that affect production, reductions in the supply of raw materials (of which 80% come from outside the U.S.), unexpected increases in demand, voluntary recalls, manufacturer business decisions, FDA enforcement actions to ensure public safety and artificial shortages due to stockpiling.

What should be done? Drug companies have always been regarded as cash cows; should they receive manufacturer incentives? Is this something the federal government should be concerned with?
