Ponder deeply and diligently in the scriptures and in the words of living prophets. Persist in prayer for the Holy Ghost to reveal to you the nature of God the Father and His Beloved Son. Plead that the Spirit will show you what the Lord wants you to do. Plan to do it. Promise Him to obey. Act with determination until you have done what He asked. And then pray to give thanks for the opportunity to serve and to know what you might do next. (Act in All Diligence, Elder Henry B Eyring, April 2010 General Conference)
What you are really saying is Americans won’t put up with the illegal wage farmers pay illegal aliens. If legal, those formerly illegal aliens would be far less likely or would refuse to do the work at that illegal wage. Farmers want the cheap labor, not American labor. Pay a legal wage and Americans will do it.
