What types of things does Ehrenreich mention in her disclaimer?

Ehrenreich mentions her good health, her means of transportation, and the fact that she did not have children in tow already set her apart from the prototypical low-wage single mother. Her being white and a native English speaker led her to avoid certain locales—like New York and L.A.—where the working class is predominantly non-white and where “a white woman with unaccented English seeking entry-level jobs might only look desperate or weird.” Perhaps more important, psychologically Ehrenreich was playing a wholly different ballgame than that of her low-wage co-workers. She wasn’t working for the money; she was working as research. “I went home every day not to anything resembling a normal domestic life,” she notes, “but to a laptop on which I spent an hour or two recording the day’s events.”
