It is not done in certain circles, and of course all circles engage in wealth (or its proxy, virtue) signalling, because we are apes who can't help themselves.

It is not done in certain circles, and of course all circles engage in wealth (or its proxy, virtue) signalling, because we are apes who can't help themselves. Dutch society pretends to be above all that, and thereby developed a neat little blind spot on its radar. That situation isn't helped by its particularly irritant way of ignoring any contrarianism until the evidence is so overwhelming we all pretend we have always seen it in this new way. Class signalling is thus more subtle, e.g. you better not sound too provincial, you can observe the way one dresses, and what clubs or sports are frequented. The usual, but more toned down compared to driving a ridiculous BMW or somesuch.
