I'd also like to point out another inconvenient fact about the progressive love for Scandinavia...
Look at Europe as a whole - you have a few countries like Denmark, Sweden, Norway, even Germany, doing well. You also have a ton of countries doing quite shitty. France's unemployment is 11%, Italy's 12%, Greece at 25%. Look further east and countries with a per-capita GDP of below $10k are not uncommon.
What does the U.S. have that Europe does not? A federal government who taxes the population fairly equally across all states and in significant proportions. Europe doesn't do this. The money supply that is within Denmark, largely can stay within Denmark. Denmark's economy, and it's population, is not propping up the lives of those living in Southern or Eastern Europe. It also helps that Denmark is not a part of the Eurozone. They maintain their own currency. They have a few limits set in place with how they can handle their currency, but not being strictly bound to the Euro like everyone else is most definitely helping them.
In order to replicate that style of socialism over here, you could do it in a few pockets of the nation if they cut themselves out of the federal taxes. If you believe Ol' Bernie can replicate it throughout the whole U.S., you're fooling yourselves.
So, yea, vote for Sanders if you enjoy living in fantasy land
Denmark is a progressive paradise because... well, because they actually are not progressive at all compared to the much more expansive United States.
