I work in Sydney Australia where we are over this hurdle. Key i think is making it a city wide conversation (where is the best place for new housing and how fast is the city growing. Its not just about the existing local residents but the wider community too), showing good examples where towers are part of a nice environment (not just 1960s public housing estates. Vancouver is a good city example who has adopted towers well) and demonstating the effect of not just 1 development but if all of ita neighbours developed similarly the city would still function.

Of course towers also open up a range of other issues like open space provision, sunlight, separation, street wall heights and setbacks, contributions to improving streets, parks, schools etc. To really be successful it needs an organised planninng approach for each centre
