The only mass they had in the 1962 was that Latin Mass, and yet practically all the clergy and laity lost the faith during the few years after.
What has happened to the SSPX laity today is the same thing that happened in the 1960's, the people have been dumbed down with insipid un-militant sermons. This was planned and executed because it is easy to manipulate the Catholic that does not have the ability to think for themselves. What ever you need is provided for you. You have a question, ask father. Give us your children we'll educate them for you. You don't have to do anything but attend mass, and transport your children, and put money in the basket.
It was that way in 1962, and it is the same today with the SSPX, and both had/have the Latin Mass.
In the big mass/school centers of the SSPX they have created a false world, insulating themselves from reality, all is well, all is taken care of, our world is good, lets enjoy life. They have lost all sense of reality. They have lost their militancy. They have lost touch with the "why we did what we did".
However, this dumbing down of the people has another effect (besides making them docile to manipulation and change "becoming the pray pay and obey zombie"), and that other effect is that they can also be manipulated by anyone else too. The SSPX hierarchy has thus planted the seed of its own destruction, as these dumned down Catholics will go with any wind that blows, going to the Novus Ordo, the indult, or even the "personal relationship with God", and loosing the faith altogether. It is the 1960's all over again for the SSPXers, the same exact thing happened then.
