So is your position that only Canadian firms should be allowed to operate in Canada in general? Foreign competition helps us because then we benefit from further specialization and trade which increases everyone's standard of living.
> Imagine that Canadian farmers, much like New Zealand farmers, make a product more efficiently than the US and start taking the US market? How do you imagine that plays out? Hint: It yields new protectionism, because the US can only win in every area.
Well, who else benefits is consumers who get to purchase products of higher quality, convenience, and affordability. Also employees of the dairy sector who face higher competition from firms bidding up their labour. Investors, who have more investment opportunities and therefor higher yield. Government and entitlement recipients who benefit from tax revenues from these incomes and investments.
