Just adding my two cents. But first, a comment on the link above from aggernodi. This link list the
average salary of occupations. This does not mean that physicians
make the most money of any profession, simply the average pay of physicians is the greatest. Everyone knows this already...with the time you spend in school as an investment in yourself, you come out highly paid vs. most other careers. I once heard "In Medicine, the floor is high, but the ceiling is not much higher, meanwhile in business, the floor is low, but the ceiling is non-existent." You quoted some salaries, but if I quote this to you
http://www.investor.reuters.wallst.com/stocks/OfficerProfile.asp?rpc=66&symbol=IHR&ID=153513, this is the salary + compensation of Interstate Hotels and Resort's CEO. If I tell you he is on the low end of the total compensation, will you believe it.
Moral of the lesson: Yes, business salaries average out a lot less than physicians, but if you can stand out
wayyyyyy above the crowd, you'll make significantly more than any physician.
I didn't even get into opportunity cost (extra salary phsyicians lose for the time they spend training: 2 yr MBA vs. 4 yr MD, 2 yr IM, 3 yr card fellow, and maybe 1-2 yr interventional for that lucrative card salary)(if you get an additional EMBA, it's usually paid by the business and most are night classes, so I exclude it here)
I think money should always be a consideration. Don't let anyone tell you otherwise. Do note that money is not the solution to all problems, but it does solve a lot.
Your decision should be based on what you really want to do later on in life, and how you want to live that life. Like I mentioned, just because there is money in business does not mean you will be making it, (There is a reason the average is low), meanwhile as a physician, you will be almost guaranteed a base salary.(watch out for government intervention though)
Lifestyles are also different, and equally rewarding and stressful in their own ways. A little research into the different aspects of each allow you to see which direction you are most likely to lean.
Most people, like Sir WO, and Taurus have given some good suggestions, but overall, I will suggest taking a closer(and perhaps personal) look into each side, and then decide which will maximize your overall happiness now, later, and in there far future.
Good Luck.
