I worry that we may be setting up some false dichotomies between feeding the hungry, clothing the naked and offering the Agnus Dei at both EF and OF Masses.
Just as musically complex modern songs (Such as the all but universally recognized on CAF “On Eagle’s Wings” with its changing time signatures and challenging range) can be taught to lay people, most of whom are unable to read music, so to can simple Latin responses be taught to the same people.
It just take a little determination to make the Latin responses available and to put up with the first month or two of people learning something new.
We go through this in my parishes every time we get new songbooks/hymnals in any language and we are adding spanish songs (such a Pan de Vida) in one parish which has been predominantly Anglo for generations. People can learn new things-they do so all the time.
I wonder if, perhaps, many posters might be valuing some of the ways Catholics reach out to the poor very strongly, but seeing different approaches as most likely to be of help.
Some posters may point to the importance of catechesis, but feel that there is such a need for material help right now, that this need must receive a bit more emphasis at present.
Another approach might value concentrating a great deal of effort into Catechesis (with the Mass so important both as sacrament and as catechesis) with the understanding that those who become very strongly rooted in their faith will have a very solid platform for evangelization which will, over time, lead to many more boots on the ground growing the faith and helping others.
I tend to lean on the catechesis emphasis myself, because I know from personal experience that it is easier for me to help the poor when I have a bit of extra, than to do so when I’m feeling pinched myself and my catechesis helps me to work on this issue. Of course, that is all about my failings; others are probably much better Christians than I am and in less need of formation.

In my case, emphasizing catechesis is kind of like the old “give a man a fish and you feed him for a day, teach him to fish and he can feed himself” saying. the more formation I get, the better equipped I am to help others and to help others help others.
May God bless all who post to our thread! Amen!
