California subsidizes the shit out of the rest of the USA, and relatively speaking gets less in return. Imagine no longer having to finance just about everything of failed religious states like Kentucky and Mississippi.

Financially it would be hugely beneficial to California to be part of Canada.

We can equally share the .ca domains, it's not like there are that many left anyway
