Although there is a progressing pattern, we can be optimistic that things also run in cycles. Similar to how if your parents were strict, you will be lenient. Then your children will be more strict because you were so lenient and so forth. At some point, waiting later to have children will start heading back down until it once again is so early that it heads back up again.
Could be the obvious fact that there is less faithfulness in general among couples. Who wants to get married to a $lu#? Regardless of how warped this world gets I think people still want a mate that is faithful (despite what the MSM says)...
We can also be pessimistic and note that, long term cycles have always ended with the collapse of civilizations and terrible tumult before the next next cycle begins.
