And, unlike the Methodists, one large issue facing Catholic parishes is a lack of potential pastors (among Methodists, there are plenty of ordained ministers but relatively few jobs; many pastors are now part-time ministers).

And this seems to be true, our churches declined for different reasons.  Protestants - both Anglican and Methodist depended on surviving by continuous and steady birth rate.  Neither of these churches, in recent times, has been big on evangelization.  I have had more Catholics suggest I consider becoming Protestant than Anglicans or Methodist put together. 
We are sexist & won't ordain with justice so we deserve to pay a price for that evil with a scarcity of priests.  However, Methodist and Anglicans have repented that sin & have equal ordination & so ample ministers but those ministers need to start going into the streets and get back to evangelizing Jesus Christ if they want to grow again.  
All Christians need to seek growth not prepare for closing churches.
