A quick glance at the world of software engineering would seem to disprove this as a claim about engineering. We have the opposite problem. Perhaps you mean that people don't want much variety and the market responds to this? Better engineering is also the answer there: the more we improve the process and reduce the costs, the easier it becomes for people to service niche markets with more obscure products. Again you can look to the software engineering world for parallels. In a world of well-engineered food, your personal "farm" is a box in the corner, which you put seed in once a week and it spits out finished produce. The coffee machine of the farming world, if you like.
