Understanding and sympathising with this viewpoint, the issue is far more one of
urban planning and
transit than it is of structure height per se.
San Francisco hasn't been known for its soaring towers (though recently the leaning sort are making headlines), but it is centralised and well-served by transit both within the city and from surrounding communities. To this extent, it resembles Chicago.
At the same time, the Bay Area as a whole strongly resembles Los Angeles, with various tech hubs ranging from San Jose to San Francisco, and including Sunnyvale, Fremont, Mountain View, Palo Alto, Menlo Park Redwood City, and Oakland. If you find yourself job hopping between these spots, commutes get long fast, and there's no one best place to live.
Chicago was built around rail with both the urban CTA and regional Metra rail service. Suburbs first emerged as points on spokes radiating out from downtown. Those have since filled in considerably, and inter-suburban commutes are both real and every much as horrible a mess as you'd imagine them to be.
Los Angeles grew up as an automobile city with boulevards and freeways, and looks it. Absent the constraints of terrain, what defines Los Angeles is a grid-pattern of both streets and freeways. Whilst Chicago does have a street grid, that grid does not define the city in the same way Los Angeles does.
If LA had instead opted to build distributed clusters of both high-rise (office/commercial) and low-rise (residential) towers, on a hub-and-spoke transit system, it might offer a far more reasonable set of commute and living options. There's no strict need for towers, so much as there is for connections between them.
Arguably, another element that defines much of Chicago is its greystone and bungalow residential styles. These don't reach the density of 5--6 story apartment construction typical of Europe, but are far denser than the predominantly single-story fully-separated housing of the Los Angeles area. As with elsewhere, density makes transit service, whether bus or rail, far more viable.
