get him after he already hit him with his vehicle.14.A wall is, of course, a physical barrier keeping people and cultures apart. There are two “real” walls mentioned in the novel. Firstly, there is the Mossbachers' yard surrounded by a fenceto keep out coyotes. But as it becomes obvious that the fence cannot fit its purpose well enough, they put up an even higher fence which turns out not to work either. This can be directly applied to the illegal immigration problem in the US. As the coyotes keep entering the yard, also the illegal immigrants will keep finding their way across the US-Mexican border. Secondly, a wall isconstructed around the whole Arroyo Blanco housing development. A stone wall and a gate are installed in order to protect the community against immigrants, criminals and so forth. But, as theexample of Cándido shows, it does not efficiently protect the neighborhood from intruders. Cándido seeks a way to get in, and finally he is successful and takes as much as possible from the people living in Arroyo Blanco. From that it can be inferred that a physical barrier obviously does not keep out unwanted animals or people. Thus the wall becomes a symbol of increasing Caucasian anxiety about immigrants.15.The ending of The Tortilla Curtain is depressing but in a way expected. From the beginning when Delaney hit Candido with his car the reader should have expected karma to come around back to Delaney. This “karma” was shown at the end of the novel when He goes to the Mexican's shack. He sees that the house is built of material stolen from his premises when a flash flood rushes down from the mountains and washes the shack, its inhabitants, and Delaney away. Candido gets his own kind of karma for stealing when him and América try to surf on pallets towards Topanga Creek, are sucked under water and can finally save themselves on the roof of a building where they realize that they have lost their daughter.16.Boyle merely draws his readers’ attention to the problems of illegal immigration. He reminds the readers’ that illegal immigration poses a threat to the national security of the United States. The author also uses the coyotes like they were immigrants. The wall that the development puts up doesn’t stop the coyotes from killing the Mossbachers second dog and it doesn’t stop Candido from discovering a way to get through and steal things. This brings up the issue that there can be no possible reasonable way to stop the immigrants coming over illegally thus Boyle draws the readers’ attention to the problems more than to the solutions.
