Median American pay for full-time workers was ~$62,000 USD in Q4 2024 (BLS), which is around $85,000 CAD. The median Canadian salary is very definitely not $85,000 CAD.
Average tax rates for people with the median income are basically the same in Canada or the US.
Looks like the USA in 2024 was $51K USD. https://en.wikipedia.org/wiki/Personal_income_in_the_United_...
I know we need to adjust for health care, but I think the median income in the USA is higher.
For WA state - we only pay federal tax so the comparable tax rate is 12% [1].
These rates mirror my perception when I lived in Montreal, Toronto, WA state.
