So long and thanks for all the fish translations! You do good work.
Also, I just want to say that this is one of the most interesting tea parties I've seen in a shoujo before. Usually what happens is the predictable "someone makes some sarcastic insinuations, and then the MC turns it around with a witty remark," and that's all there is to it. Here, they're talking about some issues with real substance to them, and it's a complicated enough issue to not have an easy answer.
This is a world with fairies and magic, so the Queen's words about the heavens helping people can't be easily dismissed as just naive.
But even without fairies and magic, what the Queen is saying isn't necessarily wrong, depending on the circumstances. It's just that Mildred's circumstances are not among them. Among friends and family, people who don't coldly count costs and benefits like an economist, generally have more satisfying relationships; but for people who don't have the minimum required to get by, they definitely need something more concrete.
