He has a decent point. He is, perhaps, not saying it very well. It generally doesn't work to use imperatives, like "Find a new city." His point might go over better if it were framed more like 'Artistic youth need a new option."
I totally get where he is coming from when he says you just need to move to someplace cheap. I am a big fan of doing what is within my means, regardless of whatever is going on in the world. But you have to be careful with how you frame such thoughts. Framing in a way that can be read as "It is your fault your life sucks" instead of "It sucks that places like New York and San Francisco aren't what they were a few decades ago. But maybe the piece within your hands is picking a new place to live that meets your needs better."
