That theory of the Bishops' policies and politics is from another time. You are right that they are hypocrites. But look at the data in your story: The US Bishops no longer make their living from donations from the pews. Hence their policy inspiration no longer derives from that. (If it did, the USCCB would function as a conservative organization.)
For decades, the US Bishops as a corporate body have built their policies, especially with regard to the poor, not around the souls of the poor, but aiming at the millions of dollars that Federal and state entities are willing to throw at them in exchange for supporting Leftist Democratic revolutionaries in our government and corporate world.
The members and functionaries of the USCCB, if they chose, could multiply attendance in the pews easily by making sure Catholic teaching is being taught and fostered at Catholic churches and in Catholic schools and colleges. But the USCCB is a creature that thrives in the Swamp (only). It promotes socialism and Leftist politics wherever it goes.
A movement promoting traditional moral and theological teaching began after WWII and has grown rapidly since the 1970s with the Pro-Life movement. These trends are driven almost entirely by priests and laymen. They have been filling the pews for decades and inspiring religious vocations, marriages, and lots of babies. The growth of the Traditional Latin Mass has also been steep and far-reaching, especially among the young. They vote conservative.
The bishops as a corporate organization fight these trends, because the USCCB is a Washington Swamp Creature. Sometimes things look complicated on the outside, but they're simple. The good news is that the new vocations to the priesthood are almost all conservative and faithful, like the young Catholics having babies.
I confess to oversimplifying things.
Which Catholic media do you access to inform your insight?
