I think it helps to also look at this from the other angle: if a buyer wants or needs a product, and it can be made more affordable to them through automation, is it morally right to not automate it? Suppose someone loves being a farmer, but you could make food available cheaper by automating it. People need food. Should they have to pay more to eat in order to allow the farmer to do what they love? If all other things are equal, it's good for the farmer to be able to do the kind of work that they enjoy. But all other things are not equal, so it's necessary to weigh that benefit against the cost. (Having said that, one thing about automation is that it requires investment, which means part of the returns tend to go to investors. So not all of the savings are passed on to the end user. But hopefully some of them are.)
