Private practice job market is all over the place right now. Some places have extenders getting $175 per hour with minimal intensivist coverage. That is just a hair lower than physician hourly salary in some places. Lots of places just wants intensivist to rubber stamp extenders' work. There are also a bunch of places that offers 90 percentile MGMA salary, with 90 percentile workload. That seems to be the trend, higher census, with lower pay/extender help, or higher pay but worse working condition.
Academia will always be around, I guess. They typically underpay like crazy...
I would encourage you to learn about the business/economics of medicine. It helps to know how and how much you bring to the employer, and how much money is actually on the table. Do that for other specialties as well, and see what makes sense for your future.
