Back in the day when the man was the provider everyday average looking women looked at that and thought, 'ok he has value that he can provide for me'. Remember a full time more or less continuous working over nearly 50 years is no small undertaking it can be a hard life. So everyday looking women used to see the appeal in that and hooked up with everyday looking guys. Now they don't the providers role has largely gone and they see little appeal in the everyday joe sort of guy. They now all chase the top looking guys, the guys that are good socially, the very wealthy guys and possibly the gym guys. They are of course competing in a packed out field of girls up against the prettier girls the more social girls, etc to get with what they see are the worthy guys, the 'good men'. Most at best just get used for sex by those men as they don't see that the everyday girl has any value other than that. The everyday girl thinks because she had sex with such a 'good man' that she is in his league and doesn't see that she isn't that she is just being used for sex. She snubs the everyday guy thinking she is so much better as a result. In the end it leads to nowhere for her and it's all too late, she'll never accept the everyday dude as she is used to dating if only briefly much better looking dudes. The generally is going to cause big problems for society going forward in terms of functionality, society becomes increasingly dysfunctional in many different levels.
Traditionally the everyday girl on being willing to get with the everyday provider guy would overlook that he wasn't good looking and see the provider element as a good deal for her. The good looking guys who were playing around would be seen as unstable and not a good bet for a content future. The everyday guy would look at the good looking girls and perve away as they presently do but they would see that an everyday girl was showing that she was very interested in them and see that she was far more and easily obtainable. So most everyday guys would accept her or if not her another one. They would get used to her looks that get to know her personality and over time her looks would grow on them not be seen as so bad and she would be quite acceptable to them. The girl would be readily available for sex and loads of other dudes would not be after her. So the appeal for both would grow and so people that wouldn't ordinarily be that bothered with each other git together and most became largely content long term. Now that has all gone and many people live unhappy miserable lives and very few people are content in life. That's not going to be a good outcome long term.
