Yes it's fair that it has more to a degree, but North Dakota can't have literally proportional since it will completely swallowed up on Congress. How does this work in the US?
Because if you consider each state to be a "country"... these states didn't sign up so that they could be swallowed up by another state having a very high population growth.
That said, California is generating more GDP so obviously I'm not arguing that they should be completely equally represented 1:1
