You're doing too much single cause analysis there.Err....in my circles its working class Latino kids that play soccer so check your privilege there.
I'm also not seeking to justify anything with low income workers. 1. I'm pointing to the unfairness of our policies that they disproportionately fall on the working class, and 2. pointing out that their work is what's driving the present outbreak, which you had originally blamed on socialization before expanding your definition.
We also know that the Xmas travel wasn't a huge driver because not everywhere in the US went up after Christmas (unless you are going to argue somehow uniquely SoCalers and certain others only traveled during Christmas).
Why would you expect a Christmas spike in an area which is already in a decline caused by herd immunity? You'd expect a mild change to the rate of decline.
Christmas spikes would be in the areas which have not yet peaked.
