You are being very very selfish and just downright mean bearishgurl. Your theory that “If you don’t build it, they won’t come” is simplistic and wrong. (Look at San Francisco, they stopped building and people didn’t stop coming.)
I am a millennial that was born and raised in San Diego, and most of my family lives here. I would like to be able to stay here, close to my extended family. Housing costs have been increasing at alarming rate. This year my rent was jacked up $250/mo. My wife and I will have to make some hard choices if more housing supply isn’t added to the region, if you had your way I would be forced to move away from my family.
Please also think about the others around you in this city who are also just trying to get by. You’re weren’t the first one in San Diego, you’re not the only one, and despite your strongest desires: you won’t be the last one.
