These days. Listen the npr shows on tinder in the last week or so and how romance is dead/hookup culture etc. Also lots of discussion on declining wages, student loan debt career prospects etc and how that's effecting dating/mating. But a lot of the blame is on men for maturing later, spend all their time playing video games and smoking weed, are unsuitable mates etc and there have been a few articles in places like the Atlantic on this.
