It is what it is. We're all making decisions which are in our own best interest. Tech people want to live close to work and can afford it. Is it wrong to make a high salary and spend your money at your own discretion? Landlords can charge more because there's greater demand. Charging less leaves money on the table unless you refuse to rent to people in tech. Are landlords really being greedy in this situation? Are we part of the problem? In a sense, yes. But is it wrong to act in our own best interest? I'd argue no - it's the government's job to ensure that society still functions despite people being inherently selfish. That said, your girlfriend has completely legitimate frustrations and I'd definitely try to empathize with her a little instead of trying to be right or point blame at something.
