I never paid for this for my children, nor do my children pay for my grandchildren, because all have attended Catholic schools (except high school for two of my children and two grandchildren).
But I think maybe a couple of things are worth mentioning. My wife and I are in two parishes for historical reasons. One does an excellent job of paying for the catholic school and the other doesn’t, and here’s why.
Parish #1. Church built long ago and well kept up by donations and volunteer labor. It’s so beautiful (built by Germans, decor by Poles) that people from all over pay to have their weddings there. They even get protestants at least asking if they can have their weddings there. (no deal, of course) Grade school (1-8) building paid for and lots of volunteer upkeep. The grade school gym serves as the parish hall for all purposes. Very unified parish that has a number of very successful fundraisers each year; some specifically for the school. I’ll never forget in one “silent auction” they held, one lady paid over $1,000 for a patchwork quilt made by the school kids. I remember another guy who donated a gold Kruegerrand for a raffle. Another donated a restored classic car. Another (a farmer) donated a whole beef he raised and had butchered at his expense. One man and his wife laid out the not inconsiderable cost of buying a full funnel cake maker, so they can make them for parish events. Tuition is $500 per child per year.
Parish #2. Just couldn’t live without building a “parish hall” (adult entertainment center)that cost millions. The remaining debt on that eats up the weekly collection. Fundraisers are few and are generally duds. Older church building that was once beautifl too, has been hideously “modernized” on the cheap. Not much in the way of volunteer labor. Parish divided, with a coterie of pushy “take charge” people who manage to alienate a lot of parishioners. Grade school (1-6) tuition is just short of $3,000/year.
Parish #2 is a lot richer parish than Parish #1, or the population is, but the weekly collection is about 2/3 what it is in Parish #1. The parish populations are about the same. Ages are about the same. The “take charge” people in #1 are very nice, and if you can pony up something significant this year, that’s fine, if not, that’s fine too. But it’s a “soft touch”, and they come around personally, unlike Parish #1 where they call you on the phone if they even do that. The teachers themselves do that in #1, and it’s really nice.
Now, I donate to both parishes and work events at both. But I’ll readily admit that I absolutely welcome working at Parish #1 and really don’t like working at #2. There’s a difference in dedication and spirit in the two.
When it comes down to supporting religious education for public schoolers, I would say the situations are probably similar. A lot has to do with just how people feel about Catholic education specifically, and about their parish in general.
But something I learned back in my political days. If you want somebody to do something, you need to ask, and in person. If I were running a religious education program, I think I would mount a campaign to “make R.E. free”. I would get some of the most dedicated parents to go around for donations, and I would put together some fundraisers with the emphasis being on the kids doing the work themselves for the most part. Once you get people to something like a fair or a dinner (which they’ll do if their kid is working a booth or tables) they’ll spend money. But you have to ask them to come and tell them why they ought to come.
