The way we describe reality is indicative of, and somewhat shapes, our perception of it. Describing the likelihood that a long-overdue increase in real wages would be cut short by a recession as "alleviating upward pressure on wages"—with "alleviate" being a word with very strong connotations of referring to removing something negative—has a pretty clear implication of wanting that to happen.
I’m not parent but I think you’re reading too much into it. There is upward pressure and reducing that can be described as alleviating without any further connotation.
