hi could someone please tell me about salaries and future job trends in this field? say if you graduate from the 2yr residency after your m.s. degree, should you be able to get a $150k/yr job in a city like san diego? or at least in some coastal carolina city? also once you get a job do you just keep it untill you retire? or you can switch to some other job? and how many hrs/wk do u work? how many weeks of vacation? thanks!
