Baloney! If scale/cost was the only issue, we would not have a problem. You could replace most processed food in a typical naive modern diet with potatoes, beans, and/or eggs (which are extremely cheap) and increase the healthiness of the diet tremendously. It is very cheap to eat healthy. The problem is knowledge. The modern processed food/ad industry in the 20th century somehow managed to a lot of destroy traditional cultural knowledge in the west about cooking and eating, and replace it with its own brand new, untested ideas. It's getting better, but very slowly. Too many people have been tricked by the newest big food lie: that choosing which foods to eat (eg, beef vs avocado) is not the most important thing, but rather what's important is the label -- it should be organic, local beef, not conventional, it must be an organic avocado, not just any old avocado. In this world view, eating healthy is reserved for those who can afford it and unhealthy industrial food is indeed unfortunate but a necessity. This world view is very convenient for food businesses, but is also wrong. In real life, the conventional potato eater is healthier than the organic white bread eater, despite spending much less money.
