Thank you for this comment, in case someone misunderstood my original post.
I'm from a working class family myself. My parents were factory workers, and they managed to buy a new 4 bed apartment in a new part of town and raise 3 children.
And yet I don't feel I'm doing materially better than my parents at my age. I definitely don't feel upper middle class even if my income suggest so. As you point out I can't imagine how people with more average incomes get by.
