Reciprocally, when low wages are available in manufacturing, comapnies are less likely to use automated proccesses because labor is so cheap it can cost less to eg. have two buckets/wheelbarrows between two parts of a factory line with one person to swap them rather than use a conveyor belt. Getting 100% automation would allow factories to come back to the US but getting that last 20% at a competitive cost is difficult.
