On top of more housing, we need better public transit. Start with running Caltrain every 10 minutes. Change local transit so that it becomes a feeder to/from Caltrain, BART, etc.
And make it cheaper.

Unfortunately, there is absolutely no chance of anything close to that being built in our lifetimes.
The problem is that unions will take advantage of all that money and increase wages and pension benefits for their workers instead of hiring more workers and increasing employment in general. This is what happens when there's an influx of money, it causes inflation.
The problem is that a lot of rich people live right along the Caltrain line and have been opposing its expansion for decades.
<sarcasm>But it's the unions' fault.</sarcasm>
Try not swallowing so much propaganda next time.
But that's a topic for another day. :-)
They're also planning on extending caltrain to downtown and connect with BART there
