In general it seems like a societal issue. Like most people prefer a bandaid over fixing the root cause. There exists public health whose purpose is to inform people in how to live healthy and/or prevent a disease. Though many don't know of such individuals or considers them as not important, where the corona pandemic was/is a good example of people's trust in them. Instead people trust doctors more to cure the cause after the effect has taken place and in lots of causes it could be too late by then.
