IMHO, it's quite hard to understand a right-leaning socialist government from the point of view of a US citizen. There's no reference.
Another interesting book looks at the welfare programs instituted in Nazi Germany as part of their corporatist 'third way' economic system (supposed to avoid reliance on free trade industrialism and inoculate against cosmopolitan bolshevist appeals): http://www.amazon.com/Hitlers-Beneficiaries-Plunder-Racial-W...
Right-leaning socialism was the original socialism in practice in Europe.
I don't buy the article's explanations thus far; though it appears to be one of a series and I look forward to reading more.
But I also am not swayed but your assertion that progress in a socialist country is too alien for we crass capitalists to gauge.
That sentence doesn't even make sense. The whole point of industrialization is to boost economic output. That's what it does almost by definition.
