It used to be, for instance, that when you went shopping you’d have your stuff retrieved for you by a small army of clerks running around the shop; indeed that’s still how it’s done in places like India with an abundance of cheap labor. But humans were getting expensive in the 1950s and ‘60s, so everyone wanted to reduce the human component, and so in that period you saw the rise of supermarkets and discount stores, where the whole innovation is getting the stuff yourself. (Sam Walton’s Made in America is a good record of what that revolution was like from the inside; consumers tended to be quite happy with the whole thing, since corporate savings could be passed on in the form of cheaper goods.) And it’s the same reason why in the ‘50s and ‘60s you saw the rise of laundromats, vending machines, self-service gas stations, and “fast food” restaurants like McDonald’s.
