It would be far easier to go after employers of illegal immigrants, but for some reason this is deemphasized in favor of persecuting a group of people who are universally poor and disenfranchised because they are a convenient scapegoat.
Second of all, you are operating under a common misconception of what an "immigrant" actually is. Migrant workers like you described are not immigrants. Drug smugglers are not immigrants. An immigrant is a person who comes to a country to live permanently, so you're talking about people who are trying to get American pay and live the American lifestyle. When we talk about deporting illegal immigrants, those are the people we are talking about. Politicians have exploited the confusion between the words "alien," "migrant," and "immigrant" to effectively dupe the electorate in recent decades and further their political goals.
