The USA is mostly empty space. Trying to force upwards in such an already dense area just doesn't make sense. We are not constrained the way singapore is.

It's illegal to build dense cities like Manhattan in most of the United States. And while most people want to live in a Manhattan'esque area, plenty (like me) do.

Spreading out requires more non-foot travel to get places. Density means things can be closer.

Seeing how elevators are akin to vertical subways I think that problem goes both ways.

Definitely had to factor in elevator time for my commute when I worked on the 38th floor.
