Tiktokers are generally following YouTuber model in how they monetize their content, minus Ads revenue share.
Would anyone with talent, skills, and self respect jump to do it?

The problem is that because of how perception can be manipulated on social platforms based on that success illusion. It makes people think that the success comes just for creating simple content, and trumps one's ability to prioritize making money to do real world things like paying rent and for food. It's borderline exploitation of children, who often over expose themselves just for likes, and that is going to be bad for their future prospects in being taken seriously when they want to get real world and respectable jobs.
It's free work with little reward. The brand deals go to celebrity creators, NOT to normal creators, while the platform profits massively and underpays most everyone who does the real work. Most of the influencers on these platforms find that even the popularity they gain fades quickly in the real world, especially as the platforms begin to decline in popularity as well, and the minute they stop working hard for free.
We need to stop fooling ourselves about it all.
It's not different than acting or professional sports; and it's far better than Facebook/Twitter model where they monetize your content with no path revenue at all. Among my list of problems with YouTube/TikTok, the revenue model is not one of them.
Vine died because quality creators left the platform, and they left the platform because Vine wasn't willing to pay them to stay. The formula is remarkably simple and for these next generations, many of them only know social media personalities. I fear that your definition of "quality content" has been shaped by your upbringing; what you consider "simple content" is "real content" for people who grew up on these platforms. I'm sure you are unaware of the thousands of creators who have millions of followers in niches you have never even heard about. While the content is "simpler" it is more diverse than you can even imagine; and thats where the staying power comes from.
