What you are describing is what has happend to almost all markets which are primarily price sensitive over time; you end up with a bifurcation of quality such that there isn't a "middle" anomoyre. Another example is groceries (specifically, meat). You used to have almost an even distribution of meat quality, from the cheapest garbage, to fairly affordable and quality, up to the extremely high quality pampered stuff. You used to have independent butcher shops all over the place who could survive in the middle. Then, people got price concious and super markets sprang up, putting huge price pressure. Ultimately, in many areas you now only have one option, which is the cheapest possible meat produced in the worst possible conditions (slaughtered in the US, shipped to China for processing, shipped back. Really.), and maybe if you're lucky, you have access to extremely expensive gourmet meats costing 20X+ as much, with nearly nothing in-between.
