“Furthermore, the fact that none of the infant burials found in Valencina have grave goods suggests that, among the communities that lived in or frequented this site, social status was not ascribed by birth (and therefore no significant inheritance of wealth occurred), contrary to what would happen later in the Early Bronze Age)32. Therefore, it is fair to assume that the individual inhumed in structure 10.049 gained a prominent social position through merit and personal achievement and did not ‘inherit’ it by birth.”

I mean… on the basis of the tombs that have been found you want to infer that? Sorry but there’s ten other stories that fit the available evidence. This interpretation really stretches credulity beyond the breaking point.
