the original OP is claiming that the healthcare industry is too profitable. So you have to compare it to something to see if it is too profitable.

Right, but why use Apple ($800 phone every 2-4 years) compared to say, an automaker ($40k in depreciation over 10 years) or a REIT ($2000 in rent every month)? Moreover, why focus on absolute profits? If the healthcare industry split into 3 (eg. doctors, dental, drugs) but with the same margins, does that mean they're suddenly not "too profitable"?
