There will always be prejudice, and the pattern of discrimination and disdain for immigrants has repeated itself almost identically over the years. Immigrants still work the more difficult and dangerous and most low paying jobs that other Americans are not willing to do.
These jobs often enforce inhumane work hours and hazardous conditions. Many employers will often take advantage of immigrants. They are also often denied breaks for meals or going to the bathroom. They might not be given the proper training or safety equipment that can make their jobs easier.
