These are all good questions, even if they're indeed rhetorical. This platform is ruled by whales and sharks with high SP, and if you follow the money you'll see that most of them self-upvote, upvote their allies and friends or they simply don't care about posting and upvoting, so they delegate to bots.

In the same time we have people with no social media skills, no fiat for investment and no education trying to make a buck, which is a plague... although in a way it's hilarious and you could make an account just to quote their comments, which would be a lot of fun!

But then you have to go around the back and understand they all came here lured by the promise of easy money. They didn't come here to found a new blockchain society or in search of enlightenment... which is basically the same motivation, that whales of today had 2 years ago!

Most of them joined, cause it looked like a good investment and NOTHING ELSE and they weren't wrong, cause it paid off big time!

Now if you wanna change basic human constitution, which is a very mixed bag, but greed is a big part of it, you can definitely try by fighting, educating, promoting initiatives, concepts blah blah blah... but eventually it's like shoving shit against the tide!

In the end of the day Steemit is a perfect mirror of a society, that decided to decentralise itself. And what happened? The same shit that always happens when power is left for grabs! It got swayed by struggles to get it, consolidate it and enforce it.

I'm afraid that there two ways to change it and they're both elusive. You either hard fork the blockchain to centralise it in hands of the few, which is back to square one basically... or you reprogram human DNA :)
