1000$ is barely enough to rent a decent apartment, in a decent neighborhood in Montreal, with maybe extra cash for grocery and hydro bill... Having a roof over my head is the very minimum I need to be safe, warm, comfortable and have privacy.
I recognize where you are coming from Mocha, looking at what your needs are and what you need to do to support them. But you must also recognize that most students (many of these SB are!) working 15h/week in a, let's say, $15/h job if they're lucky wouldn't make even that $1000. The SB accepting this amount would make it in a few hours with a SD that she chooses (she can be more selective than escorts) and even hope to have a good time compared to working that shitty student job. The SD himself, even if he's a well paid professional, would likely need to work more hours than his SB to earn that $1000 he's giving her (remember that $1000 is after taxes so he has to earn $2000 to give her $1000 cash). If he make a very decent $200,000/year salary, it is roughly $110/hour, and then take half away in income taxes so about $60/hour in his pockets. And don't forget he's likely also paying restaurants, activities, hotels, travels and gifts.
That is not to say that students should live miserably and also that those salaries paid are fair. But just looking at the hard facts, if a student in our environment decides to add being an SB to her activities, it's a good sideline. If that is the only thing she does to make a living and decides to live on that budget the SD will provide, well that is something else. But even in that case, she would have to work a couple hours a week to make a living... not too shabby!
I am not saying she is not worth it, I am not saying it's not up to him to agree or disagree. In the end, it's an arrangement (exactly!) between two human beings. However, it's easy to look at money as a numbers and loose sight of what it represent. I like my SB to recognize that what I give her is not monopoly money, it's my sweat and blood at work; just like she appreciates that I recognize the effort she makes in being sexy for me and making sure I have a good moment in her company. Mutual respect is what keeps us together.
