I don't believe those numbers (the site it comes from has interest in telling people that influencer marketing is worth much, so grain of salt.). But anyway, even if they would be true today, they won't hold tomororow because everyone gets more followers but not more attention. Also, it's a "winner takes all" market like all media. Still, if you're famous today I bet it's easier than ever to make at least SOME money out of it due to social media and the ability to cut off a lot of middle man.
You have to repeat that once a month to break into the middle class, assuming you have to pay for all your own healthcare, retirement, insurance, etc... What a dismal existence.
You mean once a month you have to make some social media posts? You conside that a "dismal existence". I know it's almost a cliche to point out HN users being out of touch with normal people, but have you ever had a real job that didn't involve sitting in a climate controlled office typing on a computer?
Despite the low effort though, being entirely reliant on online fame isn't exactly something with a lot of longevity built into it. Having 1MM followers this year is nowhere near a guarantee of growing or even keeping your follower base the next year.
$100K doesn't seem like a particularly amazing payoff for that. Most "real jobs" tend to become more stable and lucrative as you gain experience. I'd definitely prefer a job that paid $50K that I could at least somewhat rely on to exist next year over $100K that could disappear at any second.
Make ten deals like that per year, that's $100,000k.
