[Law, journalism, psychology, communications, etc. are not useless.]

I'd argue that journalism (the best journalists are those not trained academically), psychology (if you want to make an actual difference in the world, you need psychiatry) and communications (like journalism, it's a field of doubtful practical advantage) are fairly useless, along with sociology (social and economic Marxism), cultural anthropology (cultural relativism studies), philosophy (Neo-Marxist studies), free time management (it's an actual field of study here, but the people who study it are typically unemployable), history (it's a hobby, not a profession, unless it's combined with archaeology), modern second languages (hardly useful to study a language that tens of millions of people in the world already speak), European Studies (although I will say that it's a good way to get into the right parasitic networks in Brussels) and criminology (a field of study that manages to present itself as being practical, but turns out to be even more ivory-tower-theoretical than sociology).
