It will also benefit lower income employees and consumers who will see good wage/price changes relative to taxes. Another possibility is a cap on drug profits declining with drug age. This will allow enough market to avoid having to guess production costs in advance and set them in stone. The drawback is incentives to efficiency. Perhaps a mixture of price cap and profit cap would hit the sweet spot.
