His method is journalistic. He introduces his reader to a cast of individuals who serve as stand-ins for his themes. "Carla Ramos" (I don't know if this is a real name or a pseudonym) serves as an instance of the emerging generation of Latinos. And in telling her story, he tosses off an anecdote that should inspire considerable speculation on a vital topic about which Parker is seemingly oblivious.
Those remarks could use some unpacking that Parker doesn't offer.
Are these "locals" African Americans who are being displaced by Latinos? Or are these "locals" Latinos -- perhaps recent migrants or very low income workers -- who take Carla's ambition and relative affluence as a markers of race rather than class? Do "Hispanics" become "white" when they acquire education and more money? What is the role of African Americans -- a population whose absolute numbers are holding steady in both Austin and the state but declining precipitously in share of the population? Is "race" in Texas still defined in the ancestral fashion of this country as being determined by proximity in color and economic position to African Americans?
Parker offers next to nothing on these questions. I'm not ready to stipulate that Texas or the rest of the country is on its way to escaping them.
