I am glad you have sobering thoughts.
It is not my isolated opinion; there were sociological studies done of Catholics in the 1950’s, There was Altar society (aka who does the wash this week) and the Knights of Columbus. Beyond that, not much. The Social Action movement (started in large part by Dorothy Day) started to pick up individuals here and there across the US; for example, in Portland several students/graduates of University of Portland started a soup kitchen downtown in the area a lot of poor collected. it was, however, a very small minority of individuals who started reaching out directly to the poor. For the most part, it was a few here and a few there, supported to some extent by the Church. There was Jeunesse Étudiante Chrétienne, started in France as part of the Social Action Movement, and eventually reached the US as Young Christian Students; again reaching a small segment of high school and college students.
But read the documents of Vatican 2 and the emphasis they put on the laity in some documents; apparently I have the backing of a whole lot of bishops of the world as to the importance of the laity in the Church, beyond occupying pews.
Perhaps a quote from Bishop Wright of Pittsburg, during the 49th General Congregation of Vatican 2 might be illustrative of my point:
“The faithful have been waiting for four hundred years, for a positive consiliar statement on the place, dignity and vocation of the layman.” He found fault with the traditional notion of the laity being defined in Church law as being too negative; the layman was defined as “neither a cleric nor a religious.” Once the Council had declared “the theological nature of the laity, the juridical bones of the Church would come alive with theological flesh and blood.” From The Rhine Flows Into the Tiber by Fr. Ralph M Wiltgen, p. 101.
In short, it was important enough to the bishops of the world that a schema on the laity was specifically proposed and debated. Had the Church prior to that openly and actively been addressing the laity, we would not have comments, for example by Archbishop D"Souza of Bophal, India, stating “My brothers, are we - the Catholic clergy - truly prepared to abdicate clericalism? Are we prepared to consider the laity as brothers in the Lord, equal to ourselves in dignity in the Mystical Body, if not in office? Are we prepared no longer to usurp, as formerly we did, the responsibilities which properly belong to them?..” ibid., p. 187.
You may feel that the laity did much. From what I have noted, it is clear that before Vatican 2, there were movements within the Church, led by laity, in the area of Social Action; but it was coming from the bottom up, not from the leadership of the Church. I am speaking, however, of an overall attitude, from the top down, that laity were there to pray, pay and obey; and not much of anything was considered beyond that; Vatican 2 was a watershed in the Church in considering the part that laity have beyond that.
