Robert Wald Sussman said this quote

Displaced workers, along with others who fear for their livelihood, are fertile ground in which to sow anti-immigrant sentiment, since angry and frustrated people often seek some target on which to blame their problems. The right wing has organized and manipulated such anger and resentment, turned it away from corporations, and directed it against the government, decrying high taxes and the inability of the state to solve problems such as social deterioration, homelessness, crime, and violence. In addition to the target of “failed liberal policies,” immigrants make a convenient and tangible target for people’s anger. Racial prejudice is often an encoded part of the message…Right-wing populist themes are particularly effective at attracting working people disenchanted with the system.
