Again, very few people in academics are straight clinical. Just like you take into consideration benefits, matching etc, you have to take into account the degree of uncompensated time, which is a lot (research, administrative work, quality processes, resident/med student teaching, resident conference, faculty meeting, sepsis committee meeting, plus the side work I do in EMS, much of this is REQUIRED by your department). Unlike working in the community where hourly pay makes sense, it really does not translate well into being a salaried W2 employee of a university physician group. 1440 hours per year can be 100% clinical which it often is for most new faculty... Granted that clinical time can be bought down with outside sources of funding, but it can still be challenging to do.
288K/year in academics... while there are jobs out there, they are by no means easy to find, and furthermore, with all the extra work you do you are making quite a bit less than 200/hr. As you alluded to, for junior faculty its even harder, and from the research I've done on publicly available records on physician pay for state employees, the folks who are breaking the 300K mark are usually full professors, department chairs, deans of medical schools etc. This is a minority of folks in academics.
