If we make a better dishwasher that does not require pre-rinse, what happens to your argument? Is your argument that there will now be some other task, maybe loading the dishes? Consider: washing the dishes across a town employs 1000 people. Pre-washing the rishes employs 300 people. Loading the dishes employs 100 people. The factory creating the dishwasher is automated and employs 10 people. 50 people are involved in designing and marketing the dishwasher. We have now gone from employing 1000 people to employing 150. Those 850 people are now unemployed and must seek or create new employment. Whether they succeed is irrelevant though, the dishwashing process now needs fewer employees and economic benefit has moved from the employees to the smaller number of people creating the dishwashers. So your argument doesn't work for a simple reason: automation (by definition) reduces the number of people required to complete a task.
