Nordic countries are reinventing their model of capitalism
I find it very intellectually dishonest to compare Scandinavia and the United States, or any other large country for that matter.  * All in they are 26 million. The US is 310 million.
  * The US is geographically HUGE with millions of square miles. 
    Nordic countries less so.
  * Scandinavian populations are less diverse than the US.
  * The US is a superpower and must support a large military.

I don't think we can look at Sweden or the other countries as a model society. Sure, there are good ideas in there, but the question arises -- will it scale?  * Healthcare and social services -- will it scale from 26MM to 310+?
  * Infrastructure -- will it scale from 100K kilometers 
    of roads and railways to 10MM kilometers of roads 
    and rail?

Then there are issues of States' rights in the US. Getting a federal law passed is only the first part. Next, each state has to figure out how it will be implemented, added-on, or blocked.Having said all this, I don't know who we can look to. Maybe no one.
