One of the dirty little secrets in agriculture is that taste is not the priority. If you are going to plant and orchard of peaches, bananas, apples, or what ever, or tomatoes, lettuce, peas, etc. There are a whole series of criteria that go into what gets grown: does it do well in my climate, disease and pest resistance, uniformity of plant size, uniformity of fruit size, or vegetable size, does it scar easily, post harvest requirements, easy of picking, is it alternate bearing, and etc. etc., etc. One of the biggest criteria is presentability: does it look nice, have good shape, color, etc. (will people buy it). We have a tendency to want perfect fruit sand produce, even when it does not affect flavor. So those who produce fruit and produce tend to produce what we want because that is what sells. Flavor is a criteria, but not always at the top of the list.
As an aside, that is why we are part of this forum, because we want more than the 25 varieties that are mass produced for the nursery industry. Not picking on anyone in particular, but call Edible Landscape or Guerneys, or whomever and try and buy a Ronde de Bordeaux tree, or a 143-36, or a Black Bethlehem. It ain't going to happen. But we all know that there are 1000s of varieties out there, but the overwhelming majority are not available commercially. Same idea.
There are many very good tasting bananas, but they fail in other criteria. They have thin or easily bruised peels, they do not color up to a nice yellow like a Chiquita, they don't peel as easily, they are smaller, larger, different shaped, etc.
Much of American agriculture is based on a factory or manufacturing mentality - to produce large volumes of the same thing at an inexpensive price, and opposed to customized production. That is changing somewhat with the growth in farmer's markets, buy local initiatives, and such.
Not complaining or saying one way is better or worse, just pointing out how it is.
