It's a gamble. It depends when you come out, what industry is
doing well and what industry is not doing well... for example,
people study finance, when graduated, there is a rececssion or
financial crisis, then they won't get jobs...
and then you have to factor in who is coming to fight with you
for your jobs, for example cheap labor from India fighting with
local people in technology fields, etc.
generally speaking, here are some that will consistently need
people in their industry... medical field, technology, finance,
sales and marketing...
there are industry which we would advice you to avoid because
they consistently don't perform well in the job market such as arts
& crafts, sports, some wulu wulu fields like cosmologist.
