The reasons are likely pretty complex and inter-related. Some are hinted at in the article. Two reasons from my point of view: The decline in stay-at-home parents I feel would be a big one. With both parents working, the ability to cook 'from scratch' (for some definition of 'from scratch') 3 meals a day is greatly diminished. Especially with modern parenting responsibilities - try cooking that meal as a single parent with a young child underfoot. Also, cooking requires practice and intuition, which can't come from reading a book or following online guides. These skills were generally practiced and honed in families. Once a generation forgets how to cook, that knowledge cannot be passed on and must be re-learned from the beginning. This is exacerbated with family members moving away for economic reasons. The learning part takes a lot of time and some bad meals to start to get right.
