All these things will depend on location because in a standard and well-organised system of government , people who are still studying other things will still have some chance on getting employment but there are some system of government that employment can only be available to people who are concentrating on high demanding areas.
Normally the medical field will always be on high demand because it is needed on daily basis and medical doctors are needed in every areas of the world.
Anyone who is opportune to be a medical doctor will always have immediate employment most especially in a develop system of government , even in a system of government that is not fully develop. Medical doctors will always have a better chance of being employed than any other profession as I understand.
Sometimes it is not advisable for us to go for things we are really passionate about because this will not help us.
When choosing a career path , I believe the most important thing we have to consider is the present situation of the country we are interested to practice what we have study and to know the demand for such because it is not just the best for us to waste our time in school studying what will not be profitable.
