It seems to me, they are not really attempting to end their celibate condition.
I would agree they can improve themselves, by getting better qualifications and taking care of themselves and becoming better men.
However, that won’t fix the hypergamous culture that is, at least, partly responsible for they dynamic. Woman today would rather be a part-time concubine of a guy who is 6’2” and has a great job than lower their standards to date somebody who is 5’7” and has an average job.
Until the incel’s ability to meet standars and the woman’s willingness to lower her standards finally intersect, the incel is basically out of luck.
In my mind, being alone isn’t so bad if you creating a nice life for yourself and that should be the messaging disadvantaged men are receiving.
