We teach men that their value is in their accomplishments, which is a) more empowering; b) more under their control; and c) more conducive to independence and pursuit of self-realization (in career or in other aspects of life), positions of power, and yes, powerful and high-paid careers.
For example, let say we take two groups of men in the age of 30. Those in group A have traveled and accomplished a bunch of personal goals, but are at this point jobbing at minimum wage jobs. Those in group B stayed put and studied and work hard to position themselves at high earning jobs. Which group is rewarded highest by society? My bet if they did such study would be group B with a very clear margin.
Men are being taught that their primary value as human is to chase wealth. This causes men take more risk, die at a earlier age, and have a smaller social network to take care of them at old age. Regardless of gender, neither men or women live a life of roses, and being valued for physical attractiveness rather than wealth has benefits and drawbacks.
