The one thing I appreciate about Fr. Pfeiffer is that he doesn't have a lot of money, unlike Bp. Williamson. If a true restoration is to be had, it should not have wealth behind it, IMO.
I think of the great reformers in the Church such as St. Francis of Assisi, St. Dominic, St. Alphonsus, St. John Mary Vianney - none had big money behind them (hopefully I'm not wrong about that). But they were successful anyway. What they had is a great love for the Faith, the trinity and Our Lady, as well as great humility.
