Obviously because you'd rather have the housing that you could obtain by working and paying rent, which would be better.
Since most workers in San Francisco don't work in tech, that's not true. At least not if you want to live in San Francisco. The choice is a tent or a 2 hour commute, which may cost to much given service worker's pay.
The only solution is way more housing.
I agree with you that more housing is needed, but come on -- no-one prefers living in a tent to a 2 hour commute.
True, but clearly there's people preferring a mobile home.
I mean, 'you' (the speaker) could quit your job and become homeless and try it? I strongly suspect you'd prefer your original course.
