I remember that too. Honestly I think it was the explosion of social media that is the main reason. Not the only reason by any means but one of the top 2 or 3. The complete fusion of social media into dating and hookup culture. If you remember when things like myspace and Facebook first started they were heavily pushed as a tool for friendship connections and connecting with strictly friends and family. Now it's seen as normal for women to add and accept good looking men onto their facebooks and Instagrams as they are "always looking to meet new people". Back in the day people (including females) were way more hesitant about sharing personal info with strangers and random men online. Now they don't give a fuck and will open their legs for a good looking man who just added her and liked a couple of pics last week. This leaves uglier men and even average men to an extent in the dust because any average woman can just make a social media page and sit there and wait for the adds and validation from decent looking guys.
You have 4/10 fat women on Facebook getting friend requests and messages from 7/10 decent looking ripped men on a DAILY BASIS.
The proof of this is you have normie guys who are ugly as fuck or just simply plain average that managed to "secure" a relationship in 2006, 2007, 2008 and are still desperately trying to hang onto that same woman (who is now a landwhale) 10 years later even though she hates their guts, desires Chad, and cucks them all year round anyway. These oldcels KNOW it's over for them if they lose that lifeline of the whale and kids they picked up all those years ago. In 2007 that same guy might have been able to rebound through social circle game but now his rebound prospect has 15 other better looking men drooling on her Instagram page. These guys are NEVER going to get another shot in this age of unchecked hypergamy. Every normie is scared of being alone. But a woman is only alone by choice in 2018.
