Your tone is quasi-facetious, but you do not realize that Taco Bell was the only restaurant to survive the Franchise Wars, so...now all restaurants are Taco Bell.
I don't think my comment implies more corporate concentration.
And even if it does, why should restaurants be held to a higher standard than other sectors? It's fine for Google and Facebook to buy up everything, but restaurants can't consolidate?
I'm not sure more corporate concentration would be a better situation.
