That's only true if she enters into it will as an established sugar baby. Most of these women are entering these relationships without that mindset. They're looking for a partner.
A man might fan his wealth around and be generous with gift giving to attract a young woman, but that doesn't mean that he is equally generous or won't be controlling with those financial resources once she's committed to a relationship with him. A sugar baby gets an allowance to do with what she pleases.
She can start a business, get an education, learn some skills ... whatever. She can set herself up to be successful after her sugar baby days are done. She can choose when to end them too.
But these guys.... they'll plop down 30K easy for a diamond tennis bracelet, which is more about their ego and showing off but they won't pay for a year of law school for that young woman. You can't pay for Harvard with diamond bracelets and the resale value is never foing to be as much as that cash allowance was worth.
So this idea that these women are getting the best of the deal because of money is a false one, at the very best it's not a complete or accurate picture.
And don't think for one minute that these men don't play the "whore" card when that young woman straight out asks for money to secure her future after he trades up for a younger model to keep them from benefitting from the relationship.
