If you'll allow an interpetation of their comment, it read to me as them saying Trump and Harris are similarly out of touch with the common workers.
Harris even said that she only worked there for a summer to earn some extra pocket money, no one was relying on her income for housing or to be fed.
It's certainly a far cry from people working a fast food job as a second or third job to keep their kids fed, which I believe to be the people she's trying to connect with, which I see as disingenuous.
If it's even true she worked there, I wouldn't put it past a politician to lie about something like that to connect with common workers. Kinda like that republican who borrowed a family to take pictures.
But for the sake of the discussion, let's say it is true. A summer job is still not the same as the reality of wage slavery that many people are suffering through, which Harris did not.
