The appeal is also surely political since Jesus elevates the lower classes. Indeed, the gospel stories parodied the pagan lionization of emperors who likewise were supposed to have had miraculous births and who were deified after their deaths. The snarky point of Christianity is that two could play that game: why not tell the same story about a lowly Jewish carpenter? And that continued the Jewish tradition since ancient Jews saw themselves paradoxically as both lowly (perennially conquered) and "chosen" or secretly righteous.
