@Hannes -- this is constantly on my thoughts. It's a dynamic that exists outside of the Internet, too. Something, something about it is in human nature. It's in the randomness of evolution, the necessity for chaos and order.
I'm an actor. One time, I auditioned for a television show called Gilmore Girls. It was one of the only times in my life that I auditioned for a television show. I knew its name at the time, and I recognized it as a romcom that some of my friends watched. My audition received a call back for one of the lead's eventual boyfriends, and off I went to Philadelphia to read in front of the camera with a couple dozen other actors who were also called back. I read, much in the same way I had before, in front of the same people I had before. The other guys, who were there, rehearsing and preparing their reading, all looked very much the same as I did -- they all read similarly well, with minor shifts in the choices they made. I received another callback. I returned to Philadelphia a few weeks later and repeated the process. This time it was just me and two other guys. We looked even more like each other than the previous round of auditions. Our readings were, in terms of choice and style, even more similar to one another's than before.
Ultimately, I wasn't cast, and the strangeness of the experience made me yearn to redouble my efforts focusing on stage acting, which had a process that had just felt more ... organic? Possible? Enjoyable for me. I stopped dying my hair blonde (I'd seen enough blonde-haired guys that looked like me and sounded like me to last a lifetime). That shift, that not getting the role, cemented my direction (and the actor who won the role over me's direction). He's become a minor celebrity with a following of sorts, and I've become a stage actor/writer who claims that he does it all for the love of the story and the work, and doesn't care about becoming famous. Doesn't want that life. And maybe that's a lie that I tell myself and other people to protect my ego. 
The ancient Egyptians were culturally and scientifically more advanced than any civilizations that came after them for several thousands of years. So were some of the South American natives. Now, those areas of the world are some of the most under-developed and poor in our modern times. What might have happened if the Spanish had focused on North America, and the slightly-less genocidal English had landed in South America?
For that matter, what if the North American natives had been more resistant to the random diseases that the Europeans brought over with them? Imagine a world with an America evolved through the cultural influences of the natives rather than the pilgrims.
What if you/I had started writing webcomics 10, 15 years ago? What if I had joined Tapastic when it was brand new and not filled with many thousands of different titles? What if Webcrawler's initial search algorithm back in the 90s had been just a hair better than Google's? Or maybe just almost as good as Google's? How would our world be different now?
While the Tapastic community is friendlier than other communities, the power structure plays out similarly as it does everywhere else. Most people want as much as they can get, the largest slice of pie possible, and they're doing what's in their ability to get that. Growth is exponential until a ceiling is reached, and random chaos and circumstance sets that ceiling differently for every individual.
So what can you do to change that? Small things. Helping to promote other peoples' work, circumventing algorithm and AI wherever possible by being a human being. Community projects that combine the reach of many people towards a singular shared goal.
In the end, though, maybe the power law dynamic is inevitable. It's literally coded into our DNA and the entirety of our history. Random chance determines most things. You can buck against that, I do believe that everyone controls their own destiny up to a point. It's one reason why I encourage students to never turn down an opportunity just because they believe they'll have more opportunities down the line; life only offers you a finite number of true opportunities, and you never know which of those is going to give you the best roll of the dice.
Yep. So there's a bunch of pre-coffee early morning word vomit. It's a very interesting topic, though. Thank you for bringing it up in such a thoughtful way.
