It starts at home....packaged, canned, frozen food preparation, also carry out, and now the delivered to your door for you to cook meals.
I watch House Hunters and people want the big kitchen with gas commercial stove, huge refrigerator, granite counters but no one cooks in the family. It is just a show background for family gatherings one or twice a year. Otherwise everything is microwaved. And they laugh about it.
I have found that many young women and men don't know how to shop for food, read and execute a recipe, develop a quick and easy menu for the week, and feel even if they did they have no time to do it. Better to drink smoothies.
I know there are exceptions but I started as a sous chef at home at 10, cooking the whole meal every day at 13 when my mother starting working full-time. My brothers learned too.
Now that I am retired I am thinking of starting a small cooking class to teach the generations after me.
