Oh, middle class Dubliners are pretty revolting (and I say that knowing this includes members of my extended family). A few years back, they talked of nothing but how much their houses cost. I and my father were highly amused when the bottom dropped out of that fųcker. It was all we could do not to laugh in their faces while at a ghastly family wedding in 2008.
Mind you, I fear that Im your case its a class-based chip on your shoulder about jackeens that arouses your ire. I can understand your glws consternation. She believes you are better than that.
