Why does schorr think that views of history help to sustain prejudice against Mexican Americans?

Why does he believe that resentment among Mexican Americans "will not be contained "?

1. In his text "Revonverting Mexican Americans," the author Daniel Schorr talks about the ways in which Mexicans and Mexican-Americans were welcomed back to the country after WWII. He tells us that they are often the last people to be hired and the first ones to go. He also tells us that prejudice against Mexican-Americans is sustained by the views that Americans have of history, for example, in the battle of the Alamo. He thinks that such stories view Mexicans as inherently lazy and dishonest, which perpetuates discrimination.

2. He believes that resentment among Mexican Americans will not be contained because people will eventually begin to demand rights and equality. He argues that they "can be trodden on just so long." This is based on the fact that Mexican Americans are an essential part of the country, and they deserve the same rights as everyone else.
