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.
