Taking the money out of it will help reduce this evil. Porn degrades women and degrades a natural sexual relationship
Corrected it for you.
It is usually women that don't have many good options. No family, no skills, drug addicted and/or mentally ill.
And you will never stop prostitution of women attractive enough to do porn. Most of it is 1on1 private arrangements with rich guys. Basically dating that turns to “helping with bills”, etc. You'd be shocked at the high percentage of attractive poor women who receive compensation of some kind these days.
The only way to stop women degrading themselves is to increase economic prosperity for all.
