My take on the article isn’t ‘don’t follow your passion’, it is ‘in following your passion, don’t be taken advantage of’.
In a desirable field, with limited opportunities, people with financial resources can take the unpaid internships etc. so get an advantage that isn’t merit/ talent based.
The “Do What you Love” issue is then people with the resources put it all down to ‘following your passion’ rather than, for example, realising mum & dad financially supported them, and the article is stating this advice is hurting those without the resources.
One example. When I was a poor scumbag student in a recession in the early 1990’s, an 18 year old started a cosmetics company in Melbourne and made millions, won accolades and acclaim. Held up as an example of hard work and entrepreneurship etc. The founder started the company because her boyfriend, heir to a fashion fortune, lent her $40,000.
Now, great business story, obvious talent that led to success, but how much luck and privilege were involved? Not everyone has access to a boyfriend who can afford to pony up $40k. Claiming that it was just hard work and passion doesn’t take into account the advantages this person had. You don’t want a system based on privilege, you want it based on merit and ability. That’s the danger the article is warning about with ‘follow your passion’.
