I cannot comment on much recently, as in the last 5 years. But the last memory of men eager to be either servants or elders has been around 2004-5. In the congregations in my home town, there are many older men who have served in years past as elders but they are not serving now.
The majority of these brothers are the victims of elder bodys' righteous indignation (politics). After experiencing the wrath of an ungrateful body of elders who are disciplining fellow elders for minor infractions it can either lead to removal or if they move, not receiving a letter of recommendation at the new hall. Once the spell is broken these brothers find out how simple their lives can be and how much more time they have.
Imagine driving to and from the meetings with your wife and family and not alone. After the meeting, hanging around for a few minutes driving home with your family, possibly catching a snack and a few beers, margarita's, or martini's at Chili's, Applebee's, or P.F. Chang's and still getting home before you would before.
As elder body's grow older and the uber elder/nerds take over, it will be even more difficult to get someone, especially younger men interested in joining the elders men's "club". Too much work that is mostly unappreciated, others elders can be hyper-critical, and some are just window washing idiots that have no clue. Perhaps WT should change proceedure and start having the elders meetings at a men's club and pass out Cuban cigars. LOL.
