If we live in a very wealthy empire and are the wheels of production, a case can be made that our economic model, something akin to a capitalist economy could be renamed to a huge capitalist lottery. That is working for that lucky score related to the top dog syndrome, or that knuckle-crushing ladder of success.

So Medium.com is also interesting inside our system. I can't say it looks top-heavy (from what we can see) so I'll assume it's contributing to society in some way, probably because of the adage, RIF, even in the modern e-world of pacifying sublimation lifestyles. It's not full writer income for the masses of writers here, but possibly some, yet it exists, in the presents of other writer mills and hasn't dissolved yet. I guess for the writers it's how long will the grass stay green inside this fence?
