Masonry will keep on keeping on. These same stories of "numbers falling, membership failing, we are doomed" have been around in short talk bulletins since the 1930 and before. There have been many articles and books spent on the subject, and yet it keeps on keeping on. Equating numbers to success will always result in failure. All the new fancy ways to increase numbers only works temporarily, end the end you have members, not Masons.
The Lodges job is to create Master Masons. To do that you have to get people involved. To use the word of the month, proper vetting is needed. Set the expectations of candidates from jump. Then meet the expectations you have set.
