I want to think aloud for a bit, and maybe by the time I’m done I will have said something coherent and even something illuminating. Blogs are meant for experiments like this, after all.
So. Fact 1: people who make movies are pretty much by definition creative professionals*. This implies but does not necessitate that a good number of characters in movies are the sort of people who wish to pursue some sort of creative career. In any case, their proportion is considerably exaggerated.
Fact 2: one almost universal lesson/moral in many of these movies is that one should always ” follow your dreams”, even if they seem impractical.
Fact 3: most creative professions are, if anything, over-served (I think there’s a more precise term for this). From a basic econ101 point of view, this should depress wages automatically. Adding to this the fact that many of these professions are just intrinsically less valued by society, at least in terms of how much it is willing to support the average professional, leads to people being paid much less than they would get for a similar amount of work in an alternate, more “conventional” profession.
Fact 4: also consider that many of these professions have very unequal payouts. Charlie Stross had a great post where he showed that the median salary of a writer was a ridiculously low figure by western standards, even though the average is a fair bit (still not that much, though) higher, because a very, very small minority of writers make oodles of money. The same applies to actors, artists, etc. Naturally, the media in general tends to greatly play up the successes and play down the vast hordes who never make it- and no, the starving artist trope is hardly proof against this.
Fact 5: while fact 3 should ordinarily deter those without an “unstoppable” drive from making a career out of these fields, facts 1,2 and 4 considerably alter the situation, mostly by distorting reality- 1 by subtly implying that to be a real character in your own life, you must be some sort of creative person, 2 by suggesting that your life is incomplete if you do not go on to “make the most of your talent”, and 3 by strongly misrepresenting your chances of ever being successful in a material sense by making a career out of what should really stay a hobby. This leads to what is basically mis-informed consent and manufactured preferences, and you know how the rest of this goes.
Proffered conclusion: Hollywood may be ruining your emo teenager’s life.
*As you may have noted, I’m using this phrase in a slightly skewed sense here, not just the literal meaning of the two words strung together. It is not an original usage, so I think I’m safe with it. I think programming is a creative profession, for instance, like much of engineering, but this analysis is far more relevant to the miniature furniture builder or paper sculptor who quits his accounting job than to an engineer.
