LastBattle, the article you cite is full of bias and misinformation. Here are the facts.
Here is government revenue showing clearly that the
U.S has the lowest tax-rate.
Here is GDP/Capita growth showing little relationship between tax-rate and GDP growth.

Now if Sweden was in a big mess, would it not have high unemployment and be on the brink of collapse just like Greece? Especially considering that you argue that Sweden has been in a mess for such a
long time.
Well the unemployment numbers show that Sweden, and other Scandinavian countries unemployment below the European average. Unfortunately there was no U.S overlay.

Protip: Make sure the articles you read actually reflect what is happening in the world.
