Starting salary for a biochemistry faculty at many Big 10 schools is mid 70's. That is for a 9 month appointment and usually you can supplement that by about 30% with grants. Not a very easy lifestyle, a lot of pressure to get grants and publish but it's more than a living wage.
Amgen (although been going downhill for a while now...)
As I worked at Amgen, I know that starting Ph D. salary is about 90k, but this might have changed as they aren't doing so well lately.
Consulting firms also love science Ph. D., especially if you are good with numbers.
It depends how good you are. If you are good, you can make millions as a professor, consulting for a pharm company on the side.
But I'm guessing if you are good, you won't care about money, and would rather pursue a nobel prize . . or something along those lines.
I'm guessing then that you aren't that good, or else you would not be asking. Stick to business, you can make much more money that way.
