Attempting to build a language wall around Quebec is precisely the wrong policy to follow. It will keep out of Quebec exactly what we need to attract by way of talent and capital; it will drive our best - francophones as well as allophones and anglophones, with their talents and capital - to leave Quebec.
Dubai was a property bubble. Plain and simple. Go to Dubai and see what happened. It was... what I call it the 'Edifice complex' - it's just, we can grow by putting up lots and lots of buildings and trying to attract people to come here, stay here, and put up offices here and sooner or later, you put up too many.
