There's a simple test to determine if what you write is true:

Does NCR critique the salaries and finances of other Catholic orgs?

NCR indeed does that, as we can see with its recent crusade on the finances of the K of C.   

Therefore there's no grounds to make a moral appeal that it's somehow wrong for us to ask what NCR is paying its employees.

As for my salary, it isn't tied to donations, nor is it tied to appeals tied to religious belief.  However, the employees at NCR receive income that is directly tied to appeals for donations, and also directly tied to Catholicism.

In my view, this means that NCR is beholden to be straight with its readership and tell them how much it is paying its employees.

Maybe some of these employees are being paid jack, and others are being paid huge six figure salaries.
This very thing happens all over the Catholic media world, I assure you.   Catholic apologist "stars" making huge incomes and constantly asking for more $.   We have a right to know.
