Found an essay on Vargyas: it says about him:

Vargyas published his paper in the periodical of his then employer, the Museum of Ethnography. Its main goal was to represent the museum as a research institution and the work that was being done there. In his denouncement of pre-Second World War ethnographic research, he said “their main fault was that they did not recognise the deterministic role productivity and society played in progress and those eras marked by the emergence of new systems of productivity and social organisation, which was the greatest discovery of Marxist historiography.”
