It would be irrational to not expect the cost of product to increase given the times. Anyone who has gone to the local grocery and purchased vegetables (like tomatoes!) in the past few months knows precisely how much more expensive things are today versus just a decade ago.
So to expect the price of medications and the like to stay the same is very short-sided by the consumer.
At the same time, however, there is indeed a notable difference between inflating costs to reflect the assumed increases in current inflation and rising costs to produce versus outright price-gouging.
Hopefully two things occur as a result. Hopefully the fallout with such drastic increase in costs spurs the government to investigate potential price-gouging activity, and more hopeful - this spurs on another company to enter the market to help offset supply versus demand, which most of the time helps dictate (if not ensure) fair-market pricing.
To me - this sounds like a pharmaceutical company taking advantage of their position within the market. And if so - hopefully they're investigated and held accountable accordingly.
