All the winner countries are socialist leaning .
In other words socialism has never cured anything. Capitalism has created everything in this world that makes life worth living. What you call "winner countries" are far more capitalist than socialist.
No, they're democratic socialist countries. Germany, France, the U.K., Australia, Italy, dozens more. Here's a wiki for you, dear:
List of democratic socialist parties which have governed - Wikipedia
What do they have in common? Thriving but REGULATED capitalism. What Democrats have been fighting for here (not always hard enough) since the 1930s.
After 8 years of Obama, most of those countries are more capitalist than the USA.
One thing that is true about all those countries if you are born poor you will die poor. In America, you can achieve anything if you have the desire, the talent and the inclination.
This is the just one unique aspect of the United States. The right of the individual to be as important as any concept. The fact that the history of the U.S includes fighting and beating the greatest power on earth to earn your independence. Right from the beginning, America was forged to be exceptional and it rewards those who strive to be.
Furthermore, you can look even further, Americans are more generous, giving a great deal more to charity than most countries, defenders of Faith and countries who are in peril.
Without America the world would be an entirely different and darker place in 2017, you can bet your right arm on that assertion.
