You open with, "People don't move to Iowa because it's Iowa.", but then you say, "If economic conditions in Titan were similar to Norway, you wouldn't have a shortfall of migrants."
As far as the US economy goes, Iowa is a great place to live. We have one of the lowest unemployment rates in the nation coupled with an extremely low cost of living relative to most areas in the US. Despite these great economic conditions we don't have a huge influx of people migrating to Iowa.
As far as Norway goes; Norway has a fairly unique economic situation to the rest of the world due to their welfare system that is enabled by the profits coming from the vast amount of natural resources they are able to export.
Considering the huge cost and resources that would be associated with colonizing a planet I don't see how they would have an economy that bears in resemblance to that of Norway for any foreseeable amount of time after colonization.
I was trying to disprove "We struggle to get people to move to Iowa because of the cold winters" , by showing a place with harsher winters and a lot more migrants.
Maybe Canada is a much better example. People don't go to Iowa because of immigration policies, not because of the weather.
If Iowa had a policy similar to Quebec's, it would be flooded with migrants. Especially if it's doing as well as you say :)
I strongly doubt anyone but explorer-types will go to Titan in the extreme hypothesis that it becomes settled sometime soon, unless it becomes an Alberta or Alaska type with some very profitable natural resource.
