Careers or professional jobs where there is actual demand
When I say actual demand, I mean jobs where it is relatively easy finding work and if you were to lose your job, it would be rather easy finding another job in that same sort of category getting compensated similarly.
Government employees don't fit in this category for instance: if any public service worker lost their job, chances are they'd have nowhere to go and would probably need to go on EI / go back to school to get anywhere close to the pay scale they were at before.
So with that in mind, what is there out there really? Doctors/Dentists have it pretty good, but not everyone can get into that kind of career. What else? Nurses? Lawyers?
