I'm not going to do you the same disservice that you do to the original poster by mindreading, discerning that the poster's motives are not what they say they are, and instead ascribing motives worthy of scorn ("people who make the personal sacrifice to raise children to enable all of the things we experience every day as part of this human experience deserve some gratitude" -> "he’s worried about [...] not having anyone to care for and provide goods for him in his old age").
However, given your extreme lack of charity, I don't think there's much point discussing further. Any noble-sounding motive can be twisted into a selfish-sounding one and dismissed, and playing that sort of opposite game doesn't appeal to me. Nor, right now, does refuting it (beyond highlighting the example I did above).
Maybe some other day, on some other topic.
