Illegal migration makes it infeasible to invest in technology to automate the work, because any business that wants to invest in automation will be undercut by a less ethical competitor employing illegal, artificially cheap workers. This also makes it hard to attract investment for companies building technology to automate this work, because investors assume that the government will continue to not enforce the law, leading to reduced demand for labor-replacing technology. We won't get significant innovation and investment in this field until the government sends a clear message that they will be consistently enforcing the law going forward.
