Here is an interesting exercise, an objective measurement on the state of Catholic Tradition, in particular the FUTURE PROSPECTS for Tradition.

What kind of legacies are in store for the various families at your chapel? What families will disappear? (e.g., Baby Boomer couple who rediscovered Tradition in the 90's, highly fervent and involved at chapel, but their 3 kids all left the Faith thanks to Public School, Crisis in the Church, Novus Ordo upbringing, etc.)

Write down or mentally note 5, 10 (or more) prominent Traditional Catholics in your life. At your local Trad chapel, if you have one.
The more you "know them" especially his/her family and children, the better.

Now ask yourself, where will that family be in 40 years? Does he have a son that will be better than him, about the same, or worse, from a Traditional Catholic morality, truth, and Catholic culture perspective? The same for women. Does she have a daughter who could easily "become her" with the passage of years? Would the replacement be better, the same, or worse than the original?

The man who leads the Rosary before Mass at your chapel -- does he have a son who is likely to take the job when his father no longer can? The man in charge of the altar servers -- is his son knowledgeable and/or interested in serving at the altar? Could you see him running the altar server department someday? Or the man who volunteers tons of time to maintain, fix up, and improve the chapel -- does he have any children who would do so much as install a new doorknob after their father is gone? The man who leads the schola/choir -- does he have a son in the choir?

Or volunteering in general! For the prominent volunteers at your chapel (that elite 5% who do 100% of the work that needs to be done), are their children on-board such that they will take over whatever volunteer jobs their parents were doing someday? Or do they barely attend Mass themselves?

But it's not just chapel volunteering. What about that prominent couple with 10 kids? You know, the one with the mother who had really rough pregnancies for the last few (such as months of bed rest, severe constant nausea, etc.) Do you see any of their teens practicing the heroism and tenacity necessary to raise a family of 10 children of their own someday? Or did that couple manage somehow by the skin of their teeth, but perhaps they let a bit too much of the world in as they raised their 10 children, and now their children (who had much worse companions and influences than they had) will never be inclined or able to do what their parents did.

I see tradition as a whole getting worse.  Too much tv and cell phones.  Some of the next generation who just completed radical liberal college got worse spiritually.  Some left the Catholic Church altogether.  Why bother to home school and then feed throw them to wolves?  

At one chapel in our area, it was older people who ran the chapel and led the Rosary.  Their adult children either didn’t go to any church or were novus Ordo.  Once in a while, they would baby sit the grandchildren and bring them to Mass.  There were young people who would travel far to attend Mass there. 

It's always been said that the younger generation is worse than the older since time immemorial, but in these days of the Great Apostasy I think it's certainly true. And it'll continue to be that way until the end of the Crisis IMO.

Looking at a chapel I used to attend, (I’ve been staying home alone since Covid forced me into exile miles from any traditional mass.), I don’t give it much chance of still being in existence in 15-20 years or less.  There are several large families, but children gradually leave as they come of age, mostly by marrying from novus ordo or conservative Protestants.  The reason for this is obvious.  The large families are all related, most of the young people are cousins.  The average age of a member is approximately in the mid to late 50s, with no marriageable children.  There are many “individual” members, either married to non-Catholics, the only traditionalist in their family, or single and for various reasons never going to marry or have children.  There are also numerous women with a few children, either “single” or divorced, who cannot homeschool or lack total control over their children, shared custody. There’s a lack of community.  More people than not drive 50+ miles one way, cannot homeschool or have no choice but public school.  The area where the chapel is located is not conducive to young families settling nearby.  It’s extremely expensive.  A family making under six figures won’t make it.  That means either two full-time working parents, someone already established with family support, or a man with an unusually lucrative job.  It’s not a rural area so people can’t make up for food expenses by having large gardens and raising animals, or, say, burning wood for heat.  

A similar thought-exercise:

How many multi-generational families at your chapel? Since a young couple with a kid or two is "too easy", let's define multi-generational as 3 GENERATIONS OR MORE. After all, in 2021 most people live into their 60's at least, right? It should be quite commonplace to live to see your grandchildren, if not great-grandchildren. Right?

But even though Tradition is NOT a new thing, Trad chapels have been around for decades, how many chapels have large extended families attending? You know, a couple has a large family, then each of their children get married, and the ones who stay in town continue to go to that chapel -- with their kids. This shouldn't be too much to ask; I know the SSPX (which is 80-90% of Tradition) had a real low point in the mid-80's, so few chapels in the USA go back that far, but by the 90's things were building up again.
