Don't dismiss something you don't understand the need for. Even fairly poor people buy these when they can barely afford it because they need it, and there is no realistic alternative. It effectively solves a desperate problem for people in a desperate situation so they can actually sleep and not go crazy and lose their jobs or get hurt (see https://news.ycombinator.com/item?id=41286547 https://news.ycombinator.com/item?id=41286547). Humans evolved to have lots of baby caretakers, and sometimes newborn babies need to be held and rocked almost continuously- yet not everyone has that kind of help available. When my sister got one I couldn't believe the incredible disdain from older, non-working family members who raised their kids with the help of a big community that she had no way to access. These same family members that did not step in to help take care of the baby.
