A few powerful companies are exploiting the current casual/F2P gold rush, but I doubt humanity as a whole will be into casual scam games forever. Games are evidently growing up. And legislators might eventually tackle games that focus on addicting and deceiving.
All this will take time of course, but I still don't think we're in for a cultural wasteland in the near-term. Indies are already filling the gap, and it actually leads to success for some of them. Most in my circles don't focus on making money first and foremost, neither do I.
