Here's the thing: as long as poverty exists, poverty exists as a threat to get people to do things without their full consent. In some cases, like in the case of sex work, that can be actual sex, in which case, it cannot be faithfully said that all sex is fully consensual as long as it's agreed to out of survival fears. In other cases, like for example minimum wage labor, people are accepting minimum wages out of fear of having nothing, and so they accept anything. This complete lack of bargaining power is behind low wages, dangerous conditions, terrible hours, poor treatment, etc.
