It used to be that you were a guy who went to high school who didn't have a college degree, but you had a specific set of skills, and with the help of a union, you could make yourself a pretty good middle-class life.
Solía pasar que si uno era un tipo que había ido a la secundaria que no tenía un título universitario pero sí contaba con habilidades específicas, con la ayuda de un sindicato uno podía granjearse una vida de clase media bastante buena.
