GALVESTON, Texas — ­Angelica Gonzales marched through high school in Goth ­armor — black boots, chains, and cargo pants — but undermined her pose of alienation with a place on the honor roll. She nicknamed herself for a metal band and vowed to ­become the first in her family to earn a college degree.

‘’I don’t want to work at ­Wal-Mart’’ as her mother did, she wrote to a school counselor.
