Whilst I don't buy the malice (big pharma deliberately not curing things they could) argument, there's plenty of things they don't do 'cause they don't think they'll make a profit on them. Novel drug research is extremely expensive and time consuming, logically speaking a for-profit pharma company will assign its resources to the research which is most likely to make a profit. As a result rare conditions will not attract the research necessary to create drugs to treat them. To give you a concrete example, AFAIK there was never a vaccine for MERS which is a coronovirus which preceded COVID-19.
