Do you think there are less chances of finding cures or vaccines for diseases now, since pharmaceutical companies make more money maintaining people on meds for a lifetime?

Do you think that since it’s more profitable keeping people on a lifetime of medications rather than finding a cure for diseases such as diabetes, hypertension, MS, Parkinson’s, etc., there is at present, less chance of finding cures for major illnesses?

So many elderly people are now maintained for decades on very expensive medications, it seems as if there is little incentive to find cures. What do you think?
