Absolutely! I used to refer to it as the "microwave generation". Suddenly you could make dinner in 3-5 minutes. Prepared foods, a convenient store on every other corner.
I watched the onset in the early 70's with the popularity of the radar-range(before microwaves). Suddenly our mother had one, and a freezer stock full of frozen meals. She only cooked on the weekends. Convenience only created laziness and sick people.
