Eventually the price will go down to the point where only the people that care will remain. I'm not sure where this equilibrium point is, but once people get over their ROI mindset, they'll either move onto something else they can exploit or they'll learn to be people again. The only thing we can do is reward the content we find valuable and post and talk about stuff we find interesting.
Ironically, I think Steem's largest obstacle to adoption is the fact that it has some monetary value in terms of other currencies. It kills the social aspect of the whole thing and people simply run "mining" bots to maximize returns on the token.
I agree, the fact you "get paid" means there will always be someone looking to make maximum profit fast, I just wish it wasnt so prominent :(
