Never heard of research investment, huh? Or testing and registration expense? Nor, evidently, are you aware of overhead, packaging, sales and marketing expense or any other business expenses.
Obviously, you know nothing of accounting. Nor anything about the pharmaceutical industry.
If Nexium cost half as much, people would likely buy 2-3 times as much of it. Instead they tend to only use it in emergencies, and not use it for more than half the time they could use its benefits.
Don’t jump to conclusions here. We own our own business. I know what things cost. We also work very closely with our chemists. I know what things cost. Pick a medical product and price it out at Costco....you’ll be amazed at the difference in cost.
