Yes, the "everyone" being alluded to is a pretty erudite circle, but hey, you know you're talking to a snob. ;-)
There is indeed a "What if?" question, for "What if I had continued to study Greek?" Instead, as you know, I've been through tremendous misery with Chinese and Japanese since then. However, I have zero faith in Greek culture: I honestly do not think I could ever have a job in Greece, and I do not think I'd have friends in Greece —I have one Greek friend now (internet-only, we've never met) who very much rejects my understanding of the modern culture, and who insists I'd do very well in modern Greek culture, and with the modern Greek language. If my daughter does actually move to Bulgaria, I would indeed consider moving to Greece, and learning Greek (again). And yes, the years I spent studying Pali actually do make it easier to learn Greek (ancient or modern: they are really, IMO, the same language to a greater extent than the British ever want to admit, i.e., because the British insist on pronouncing Greek words with a British accent that they pretend is "authentic" ancient Greek).
