What is up with the first paragraph of the reply? WTF? either 'cultural differences' is correct, or it's racist, and since in this case it's supposed to explain that the reason a Black aide would steal someone's stuff and sell it is that this is Black culture, I would say it's racist.

That said, "people of color who work in the medical field deal with racism from older white people all the time." is sadly true, and so is the fact that people suffering cognitive decline often spuriously accuse caretakers and support workers of theft in general. The intersection point is really fun, as one can imagine. I do agree with the bulk of the advice -- don't fire someone who needs a job enough to do this difficult job, and don't engage in racism by trying to protect someone from it (the long term solution is to never hire Black aides, which is.... racist) Instead apologize to and thank the aide, and definitely include a gift card.
