Why do people play the lottery? From a statistical standpoint, it’s a foolish waste of money to buy a ticket, yet someone HAS to win eventually. Yes, if you’re buying a lottery ticket as part of the “redneck retirement plan”, that is, viewing it as an investment or more than a fleeting hope that it will pay off, that’s bad. If, however, one sees it as a few bucks of entertainment to dream about the possibility and then a little bit of excitement seeing the numbers read, seeing one or two match from time to time, maybe even winning a few bucks here and there (though a loss overall). Sure, it’s still a new loss, but maybe that cost is worth it to them and I understand.
This compares well to these sorts of dream professions. There’s always a new pop star or movie star breaking out every few months. There’s always the next NFL/NBA/MLB/NHL draft, and there’s going to be future all-stars and hall of famers and championship winners in every single draft. Yes, the chances are slimmer than the effort put into it would tend to be worth, but we have a tendency to over-value slim chances and undervalue more likely chances. It’s not unlike how we tend to fear terrorism more than a car wreck, even though we’re thousands of times more likely to get injured or killed in the latter. After all, someone is going to be that next star, why not me?
But I also think you underestimate how many other careers there are that are less glamorous in these fields. As a huge fan of underground music, the overwhelming majority of my favorite artists are often able to make out decent livings after putting in a lot of hard work. Could they have made the same amount or more money with less work? Possibly, but they get to do what they love. Maybe they started doing it with some aspirations but with fallback plans. Hell, many of those bands have “day jobs” that they have to take time off from just to tour and it’s not until after they’ve built up enough of a following that they can make their bands a full-time gig. Even then, considering how hard they have to work, they’re probably still under paid. But speaking for myself, if I could do one of my true passions for a living, even if I had to consistently put in 60+ hours a week and make less money than I do now, I’d do it. Hell, between my job and the time I put into my passions as it is, for which I’m not paid, I put in at least that much time. That fulfillment and getting that much more time in what I love would be worth it.
Same goes for other professions. One can pursue a career as an actor and make a passable living without ever being the next Brad Pitt. I’ve personally known a couple guys who would get a few small parts in TV shows from time to time. They’d also do small indy films, commercials, some stage work, whatever. Both still had some side jobs to fill in when they weren’t getting regular work, but they seemed to love what they do. Similarly, I’ve met some minor league baseball players who were able to have decent length careers making decent money and then they used their downtime in the off season to get better educations or investments or work in other fields to have a career to follow up.
And that doesn’t even mention all the countless other jobs in these fields. Maybe one starts out hoping to be a musician but ends up in production or management. Maybe one wants to be an actor but ends up being a writer or director or stage manager. Maybe one wants to be an athlete but ends up being a trainer or position coach or agent. When we think about a film, we only seem to pay attention to the lead and supporting actors and maybe a few people behind the camera like a big name director, producer, composer, cinematographer, but there’s literally thousands of people involved in a typical wide-release film.
So, sure, if one wants to be a big name in one of these things and isn’t willing to settle for less, they’ll probably burn out and end up waiting tables or serving lattes. But I think it’s ultimately good for society to have people that dream big, even if most of them fail, because many still land on their feet. Hell, even outside of these glamorous types of things, this is what creates innovative business ideas, inventions, whatever. Society people, most people, to find a good paying steady job, but society also needs big dreamers willing to take big risks and potentially fail big for that small chance at glory and possibly doing something to further humanity.
