Good Question...
70 percent of men aged 20 to 34 are single
That means A LOT of not only men but women who are single...
Per Mormon theology, that trend (along with the trend away from Mormon temple recommends) means the overwhelming bulk of Mormons wont qualify to live with Heavenly Father forever.
Simply because of those 2 missing elements: An eternal marriage & no temple rec
Even if single women get the temple rec, no hubby, no living with Heavenly Father eternally...eventually, the Lds gen authorities may have to round up all these single women into Mormon harems...for their own eternal welfare, mind you.
...where you can match with 29 women in a different dimension.
