One way SF planners made it hard/less economical to build towers was to force the higher floors to be smaller than lower floors (Transamerica pyramid being the near-satirical example).

That has contributed significantly to SF's inability to build enough housing for the people that live there.

Also a dog-whistle is any statement that sounds palatable to the mainstream, but has an underlying meaning to a politically motivated group. It doesn't only apply to today's American right.
