You're still not accounting for greed and basic capitalism. Something has to force failing ideas and products down. If they are already monopolized and without any forseeable competition, it will not matter. I doubt a group of shareholders are just going to say, "yea, alright, were making more so lets drop our prices." This was the theory behind trickle-down economics.
Now, however, perhaps I'm not taking into consideration a complete new way of doing things OR the effect it may have on many other not yet existing industries and services. BUT, that doesn't stand in the face of things like power, water, internet, fuels etc.
