I agree this is a very relevant issue for so many Trad Catholics. Much more relevant than, say, the current juridical status of Pope Francis.
It is also more complex (and should I say, "interesting?") than the easy-to-describe and easy-to-comprehend case of the small family of the convert to Tradition. I have mentioned before the classic meme of the Baby Boomer who is a huge volunteer and pillar of the chapel, makes big donations, but:
* His extended family/kids are never seen at the chapel.
* He and his wife only have 2 or 3 children - they left childbearing years before finding the Catholic Faith and/or Tradition, so they are "off the hook" so to speak
* They are therefore materially well off -- nothing they can do about it now
* They have plenty of time too, since they are well off and/or retired, and don't have many kids or grandkids to occupy them
I say: those people BETTER volunteer and get out their checkbooks; it's the least they can do to show God their good will. I'll go one further: they should be grateful (rather than condescending) to the large, usually poor, young Trad families around them, who can only manage to donate $20/week to the collection, and little of their free time, because they are busy raising a bunch of little Catholics for the future. Something that (even though they are technically guiltless) THEY THEMSELVES objectively failed to do, to a large degree.
Don't get me wrong: hooray for these converts. God bless them. Let's face it: what else can they do now? Exactly what they're doing: Volunteer, be generous with all that extra money. But as part of their penance, they should be willing to understand and be charitable to those young families struggling to raise large Catholic families in 2019, which is almost a heroic feat. Even if they had 5 or 6 children back in the day, 2019 is NOT 1980. The dollar has been that much more devalued, inflation has done its thing, and certain things like college and health care have skyrocketed over the past 30 years.
Someone has to make more Catholics, altar boys, future priests and religious, etc. And that is hard, long, expensive work. Much harder than simply cutting a $2,000 check every month for the collection, I dare say!
