Again, I am not making comparisons adjusted to salaries. I'm just proving that claims that the cost of living is "just as high or even higher than the US" (not adjusting for salary) are false. Simply looking around Vancouver on zillow proves this to be obvious. For example, I found multiple 3b2b houses with backyards for under $3kUSD in nice areas walking distance from central Vancouver, which is literally impossible in SF.

Otherwise, as I already stated, we agree that it is almost always better from an economic perspective to live in San Francisco as an engineer, given the vastly higher salaries.

NOTE: I'm specifically responding to your claim that "the cost of living in Canada is just as high or even higher than the US", in the context of HCOL areas where tech workers typically reside.

Honestly I don't know what can convince you, so maybe we can just agree to disagree.
