Social Blade can be really accurate. It doesn't use facts, but an algorithm, but even that depends on the YouTuber. When I was researching starting a channel, I learned that how much money I make depends greatly on how well I play YouTube's game. Sadly, that includes semi-clickbait-ish titles, explosive keywords, being their definition of advertiser-friendly, and their preferences for how much/often you upload content.
You can still make decent money on YouTube. For a van lifer, you can do pretty well with just a few thousand subscribers. I'm not going to lie, this appeals to me because, for me, it's much better than trading my time for money at a 9 to 5. That's just my preference based on my experiences. But, there is a certain element of selling-out to do it.
No matter what you do, though, there's always give and take. Good and bad. Freedom vs The Machine. So, for me it comes down to this: A 9-to-5 (trading time for money) vs Freedom of my Time (still working, but on my own terms). Oh! Another thing I've learned? There's an audience for everyone and everything... no matter how overdone, obscure, or obsolete.
I chose van life, and all that goes with it, because I want the freedom of my own time. I've been a good boy and played the game long enough, and it got me nowhere. Whether it's YouTube or not, I will be working for myself in a self-employed, entrepreneurial way. Oh! Another thing I've learned? There's an audience for everyone and everything... no matter how obscure, overdone or obsolete.
