As teenagers, women expect a man to have a car. A car is crucial, and no socially conscious young woman will date for long a wonk without wheels. A guy with a car can take you places, but a man with money can show you a good time. So women want wealth. If you don't have money and you're not macho, then you're not a real man.
Credentials mean power.
Power to move through certain spheres of influence, power to command certain kinds of respect. They know they can be caring, affectionate, sensitive and nurturing, attentive and good listeners to their wives. Ultimately, this led men to educate, elevate, and emancipate women. It should come as no surprise, therefore, if pop feminists attack men for not being chivalrous. Chivalry provides many benefits women are reluctant to give up.
