The support for "being treated well" in the Daily Mail article is a letter written to her family, one month after arriving in the US. That's not strong evidence for the claim. One, it was only after one month, which may not be representative of the rest of her working time. Two, when people aren't doing well, they don't always tell their family so, because they don't want their family to worry.
