You're comparing oranges and apples. During the time of Trent, the problem being addressed wasn't just the corruption, but the schism of Protestantism. Now, we have modernism, which is "the sum of heresies," in the Church. A large part of the problem is the liturgy. It is valid, but it is spiritually-poor, compared to the traditional liturgies.
Nope. I am comparing apples and apples. There were innumerable abuses, superstitiuons, worldy music that were abuses in the old liturgy
That, of course, is your opinion.
