Why are there many young men who prefer not to spend money and time on dating women?

I have never been interested in having a girlfriend, nor do I invite any woman out to dinner. I thought I was a minority, but at my university I have met too many men like me.

I understand that there are many people who are upset that there are men who prefer to follow their goals and not spend money and time on women, however, they will have to get used to it, because the liberation of men is imminent.
