A lot stems from the late 18th century concern that filthy immigrants were making unhealthy food in local bakeries. It was better -- so they said -- to eat mass-produced breads baked into identical loaves with small, evenly distributed air holes by clean machines and in a pure, clean white color to make it clear there weren't any bugs or other impurities.
From there it was a process of mass industrialization and tweaking the ingredients to minimize costs and optimize baking times.
Generally food in the US is sold for size, not flavour or nutritional content.
For example US roaster chickens are huge but basically live short sick lives and taste bland.²
Chickens sold in France are smaller but have more flavour.

Food quality might be lower on average, but saying the US has no food culture is just snobbery.
A proper family bakery where bread is just the 4 basic ingredients or sourdough etc, and the pastries and cakes taste home-made can be really hard to find now.
Thus you get US Bread.
If the US is the outlier the question should be what condition that are US specific made it happen, not a general concept like greed.
The lack of coherent food culture I have considered and it might make sense and it would explain why the US is a special case.
Demand for cheap food exists everywhere.
Not sure how culinary standards got worse, depending on what standards you are talking about. Many things got better in most food groups.
Good bread, as with any good food, typically takes time and quality ingredients. You won't find that in mass produced food. That costs too much.
The problem is that after about 24 hours it gets hard and after 48 it's basically inedible. So your diet needs to include a lot of bread or else you end up wasting a fair portion of every purchase.
I bake sourdough and other breads every other day at home but baguettes are one bread I have not been able to get right yet though I haven't spent enough time trying to figure it out. I know there must be one simple step I'm not doing or doing wrong.
Collectively they are :-)
