Redpill always "worked" for certain men, it's just that the bar gets higher and higher. For example before internet a 5/10 NT guy could get successful with proper game if he really tried. With internet the bar slowly moved up to 6 and now with Tinder I think you need to be a 7/10 to get benefits of game and red pill in real life.
I think the main problem with redpill is that with internet and social media, you can't really pretend you are this successful alpha male any more because everyone can just check your social media account and get a basic idea who you are.
Like for example if you're a sperg like me, you can't just pretend to women that you're this popular guy who has a lot going on for him socially when they could just add me on Facebook (I don't have one anymore, but I used to) and I see that I have like 50 friends with like 7 people liking my pictures. All of them men of course.
So with internet in equasion, I have to be honest about being a loner of some sort. Now what game can I play as a loner? You just end up looking like a creep.
