I don't understand how you mean that long text addresses the issues raised by me and others.

From what I can discern, he makes two counter arguments:

1. Sex is as important as income.

2. Poor income leads to "poor access" to sex. If the income distribution is unfair, so must the resulting sex distribution be.

To 1 I can only respond that many people feel differently. Anecdotally, I've never encountered anyone but well off men making the argument. Is that your experience also?

For 2: Poor income leads to many unfair situations. Let's cure the problem and not the symptom.
