Yes, the lukewarmness of many traditional Catholics has been a big problem. It is default for some conservative Novus Ordo too. No wonder God does not answer our prayers. I have been guilty of it myself whenever I want to be indifferent about something that does require zeal or patience.
It is a lot of sloth including laziness that plagues us today. I imagine the groups more distant from the Novus Ordo in their positions would more likely have zealous Catholics. The SSPX and others getting more chummy with the modernist occupants in Rome have more of the lukewarm types. Simply put, they have more attachments to the world.
