More housing where the jobs are creates less traffic. Putting your jobs in Berkeley and your housing in Vacaville is what creates more traffic. A Berkeley with 300k people - which is the population that would support the number of jobs already in Berkeley today - would have noticeably less traffic. Same for a San Francisco with two million people etc.
That’s true, but it is difficult to do in the USA since the company town concept/complex fell out of style in this country after WW2. People don’t generally live where they work, especially if they bought 10 years ago and switched jobs twice since then (and that isn’t even counting second body problems). Transit is really needed to fill in the gaps, or perhaps renting should be encouraged so people more easily move when they change jobs (but the second body problem remains).
WFH works also, but then you don’t need to be near where your jobs is.
Tenure of homeownership has more than doubled in the last twenty years, and it is a harmful symptom of the housing crisis, not something to be accommodated. When the housing market was more functional and job mobility in America was more robust, people only owned homes for 4 years at the median. That was the same as the median tenure at jobs. That’s the way it should be.
That isn’t true in other countries, like most of Western Europe. It isn’t how it should be, especially if you have kids (yes, I moved around almost exactly every 4 years as a kid, it sucked). Good transit in urban areas with a lot of jobs is a wonderful combination. Also, husband and wife don’t need to work in the same neighborhood, which is highly unlikely as you go up the skill chain.
Prop 13 is responsible for the extension of tenure, since when you move, your property taxes are reset, and this creates a strong incentive to stay put, across multiple generations as well.
That is disingenuous. A lot of SFH owners like driving cars, dislike transit, and therefore are of the mindset that more housing = more traffic. Density of course needs mass transit if it is going to be feasible (you don't build a 30 story apartment building away from transit and expect that to end well).
It also increases the need for new infrastructure, such as electric wires, sewer/plumbing, trash/sanitation, schools, police, fire stations, etc. You can't just plop Moar Housing down and call it a day. You need to build these things, too.
More office space also contributes to increasing traffic yet curiously there is no widespread, organized NIMBY opposition to offices like there is to housing units.
