I am not, so I would have insurance, but there are many that would choose to go without, which drives prices down (lower demand), even though I'm paying for their stupidity (my insurance would cover damage to me and my vehicle regardless of fault). Not to mention actual COMPETITION.
Also there is absolutely no way any company would continue to bother with a near 0% overall return, regardless of whatever side business keeps them afloat. What happens is budget gets assigned to departments, and is marked down as 'spent' (or one department pays another for services, so that the insurance portion of things looks like 0%, but there's income from whatever business the one department does for the other) and we see a 0-4% profit margin. There's lots and lots and lots of ways to make numbers tell whatever story you want.
I mean, all that, plus Brampton...
It's just unreal how people defend the industry here though, everywhere else in the bloody world insurance works for less than 5-10% median income of the population.
