It shouldn't really surprise anyone though, should it? Psychology suffers the same problem professional writing nowadays suffers from: a whole lot of supply and not enough (paying) demand. The degree is almost as popular as law, but without the omnipresent demand and highly marketable and tangible skill set. Psychology does not have omnipresent demand and a highly marketable and tangible skill set. Just about every private company in existence needs some form of legal services, only a tiny fraction require psychological services and you can't justify employment because you've done a strenuous degree and are obviously a hard, clever worker like science, law or medicine grads.
Psychology as a science isn't at the stage where it's producing enough tangible practical applications that need specialised knowledge to support the amount of people studying psychology. There have been a lot of breakthroughs made - cognitive behavioral therapy is one of the most visible - but not enough people need CBT for anyone to go around saying 'I have a Bsc Psych and you should pay actual money for my expertise'.
A lot of the stuff is applicable for things like market research, but it's not valuable enough that companies desperately need YOUR expertise instead of the expertise of the marketing & management science student who can read the relevant material but has spent three years getting wired, drunk and laid with all of the better connected business and econ students. After all, you don't require the specialised knowledge to apply psychological research to marketing that you would to apply legal knowledge to defend someone in court, or medical knowledge to dispense prescriptions.
Let's face it, the applicability of psychological research is often a stretch. You can see it in the discussion sections of 90% of published academic papers - an interesting premise, fairly mild results and a desperate attempt to hook those mild results onto anything outside of academia. Study shows that reaction times are marginally better for seeing dots appear on a screen if the voice giving instructions is female? Applications for Sat Nav systems! Study shows that opinions are polarized when discussed in groups? Vaguely defined uses for management!
Most of the time you're thinking 'k that's cool, but how is this valuable enough to get paid?'. There are areas with more applications than others, behavioral finance and anything done by Elizabeth Loftus come to mind; but in the end it's still like being a writer: how the hell are you going to get paid with all of this competition driving the prices down?
