Single

People have never more single in our history and the mechanics of how we got here are easy to understand. We removed the business model aspects of marriage which necessitated that each person bring something to the table. Once women became more independent many men became expendable. 

It is why we have a crisis of masculinity and why hypergamy which is what sees 80% of women compete for the top 15% of men dominates the dating marketplace. If men have height, looks and money they have their pick of more women than the men who are left behind. 

In addition those people who are older and understand all too well the benefits and the pitfalls of couple life are deciding to not enter it again unless it falls into their lap. Some make friends with benefits arrangements that don't involve cohabitation.

Whether this changes has a lot to do with how society restructures itself once we come out of this 100 year historical cycle.
