Some people really gravitate towards a shutdown mentality. Indeed, if a country could be perpetually disrupted or shutdown, that would dramatically reduce the influx of people.
Most of the world is non-white & Canada doesn't even have 1% of the world's population. For some, just to think that Canada might contain half of 1% of the world's' population is too much. There is a reluctance to improve & expand on infrastructure, because that would mean building for more non-white people.
While the British Colonial mentality has been gradually fading away, there is still a strong KEEP THEM OUT mentality. That's especially been the case in BC with its reluctance to build up a proper level of infrastructure, is very apparent.
