This seems very different that what the article describes.
Sure, some young people may spend more than they can really afford on their wedding, but this still seems like a personal choice - tons of people have cheap weddings (or gasp, elope). I don't think may people are cutting back on eating (when they already suffer from malnutrition) to have a big wedding like how the article describes funerals in Zimbabwe.
Plus, I think the relatively few cases in the US where young people do feel intense family pressure to overspend on a "big wedding" show similar dynamics and downsides to the "kinship societies" that the article is really about.
