What benefits do men get from being a provider?

I just don’t understand. My idea of a relationship is both partners giving equal effort so whenever I see people clamoring for a “provider man”, I just don’t understand what the guy is getting out of that kind of relationship. Aren’t both partners supposed to be giving and loving each other? I’ve asked many women what I’d get out of a relationship like this and they always say they’ll take care of the house and cook but those are very basic chores that everyone needs to do already. What are the benefits here?
