Honestly, I think Steem actually makes this view of social media outdated. People are more likely to do things for money than they are for "likes" or "social acceptance". The only thing you can get on most social media sites now is "social acceptance" or "street cred". Even Facebook hasn't found a reliable way to bring actual value to its users. People are more likely to flock to steem just because of the money aspect of it. People are currently working so many crappy jobs/ doing any number of unsavory/ illegal things to get money. You don't really see that many people desperate to do these types of things just for likes. The survival instinct that Steem taps into is much more powerful and universal than surface level narcissism that most other social media strokes.
