I think that the only thing a beta needs to get his shit (at least partially) straight is a dose of redpill truth in the form of an example. The first step I took to a kind of redpill mentality (before I found this subreddit) was when I saw that guy in war at home tell his son that the only way for him to get a hot chick is if she goes through a few husbands and divorces and has a few kids.

So after contemplating on it for a while and after a few reeeeally bad experiences with what I know now is hypergamy I came to the opinion that I can state as such:

Why should I give half of what I own, half of what I AM for a chick that has spent her youth giving herself away for free to the point that there's almost nothing left and nobody wants it anymore FOR FREE.

So basically a beta will stop being a provider if you show him his future and give him some time to think.
