Sweden, Norway, Denmark, and Switzerland all have no minimum wage... my point is when progressives say "adopt their model" do they mean 'adopt their model'? or are they cherry picking the aspects of the Nordic economies they like?
Regressive relatively flat tax rates 
Higher economic freedom
Little product market regulation
Again, those talking points are so distorted as to be meaningless.
Sweden doesn't a federal minimum wage because strong national workers unions set industry-wide minimum wage for every industry. Even fast food workers and hotel employees make close to $15/hour minimum.
Federal gun laws in Scandinavia are generally stricter than USA, not looser
Most Scandinavian nations are part of the EU which has greater product market regulation than the USA in many respects. In others, the union power and strong stakeholder economic model creates stronger industry standards absent in USA.
Sweden can have fairly flat-looking taxes as all kinds income up to something like $60,000 is free of federal taxes. Finland has very progressive tax structure. And heavily subsidized basic services make the system far more progressive than taxes alone an demonstrate.
Economic freedom is indeed generally higher, in large part that's due to the political lobby system and corporate crony American laws which create obstacles to smaller businesses in order to advantage powerful ones. But some aspects of what are called "barriers to economic freedom" on the USA, like environmental protection, are strong in Nordic countries.
That's what I mean by context.
