I'm not going to call out any names but there are several posters here that boast waaay too much about their class and believe in the just world hypothesis.

Not everyone here grew up in a loving, stable middle/UMC household. It's easy to find love if you did imo as you will be socially and emotionally well adjusted enough to find a quality mate early.

It's a lot more difficult to succeed if you grew up in an unstable, economically disadvantaged household. You're likely to have "baggage" at a young age and you'll only be able to relate to other maladjusted people who are low quality dating prospects.

Even if you work on yourself and go to therapy/meditate you'll be at a significant disadvantage bc all of this takes time. Most quality people get taken early so you'll have to be incredibly lucky with timing. Furthermore you will have accumulated baggage from dealing with low quality people.

Tl;dr it all starts with childhood/upbringing. If you were abused as a child and grew up in a poor, unstable household it will be hard for you to find a quality partner
