At least here in Germany Aldi isn't even really limited to the poor, it's famously a place where you can run into anyone. Where I used to live in Berlin close to the government district I literally on occasion ran into the chancellor (and her bodyguards). Aspirational shopping where you buy premium goods to pretend to have higher social status honestly seems a bit on its way out. Even middle class people seem to consciously shop more utilitarian now.
Spirit was broken by oil prices which everyone pays the same for. (There is no cheaper jet fuel alternative).
Not a good comparison to the point of wrong conclusions.
