Big metropolitan areas around the world have a lot of diversity. For most of Vancouver's history, it was just another British colonial outpost & backwarter. Hence, the short trains, narrow bridges and small buildings. Vancouver & the greater region are just starting to become a major urban area. BC has less people than Switzerland & Canada has less than 1% of the world's population.
The KEEP THEM OUT mentality & agenda has been firmly entrenched for generations.
Perth & Brisbane gave up on being provincial backwaters decades ago. Melbourne & Sydney were never stunted by anything like Vancouverization or the backwater BC mentality. Even Adelaide is emerging as a fine state capital, instead of just being like another provincial backwater.
