Value Your Worth

Everyone and everything has worth. Worth however is not always valued.
Using someones image for promotional use or event hosting to gain your own profit means someones value is worth something. If an image did not have value, there would be no sense to use it to help you gain, right?
Every time an image is used for promotional use, that promotion company gains value in their net worth and most of the time in their pocket. Why then, would you think it to be ok to ask a model to "volunteer" her image for you to increase your own value when the most value is coming from her.
Most models invest a very large amount of money into themselves to network their name, to gain a future profit. Money spent is money earned.
Men take women on dates and spend money to please women and they're not gaining a profit from that. Why then, would they not want to pay to use someone else's image, for promo or in person to host events to help you gain your own profit? Its like a relationship. The only kinds that work are the ones based around interdependence. I do you for you what you do for me. Use my image, pay me!
