I'm not sure I agree that lower steem and SBD prices will improve content quality because I'm not sure I agree that people spam, scam, plagarize because they are seeking high SBD/Steem, but in fact because they are looking to acquire a crypto, regardless of its price.
If Steem was like 0.01 USD perhaps that would mean lame spam/scammers would disappear because then the reward would be perhaps too minimal, but unless we get down that low, I think spam/scammers will stay, unfortunately.
you may be right. but there is always hope
