I keep hearing the idea that provider-men are often seen as more desirable to women and that the higher the income the greater the mate value of the man. This gets explained using evolutionary biology stating that men with higher income signal traits that women select for such as competence and ability to secure resources which is beneficial for offspring.

That being said, with the current state of our economic system increasingly more money accumulates within the wealthier, upper parts of society making it harder for the average man to earn a decent wage decreasing his mate value. The implication would be to try and change the system but that feels difficult and unlikely to happen soon so is there any other way men with low-incomes can be of value to women? How can men, especially those without decent wages be desirable to women in this unequal world?
