"From the French Revolution onward, the children of the bourgeoisie had conspired to destroy democracy"
There is a subtle error to this....they seek not to destroy "democracy", but rather "free market capitalism".
Europeans are steeped in a tradition of socialistic thought that stretches back to the mists of history (from which they only emerged, briefly, during the Enlightenment before slipping back into barbaric collectivism). The European intellectuals (and much of the people) hate America because its based on individualism and free markets...which they consider to be vulgar and materialistic. Yet, they know, deep down, that all of their goofy collectivism has only resulted in murder, pogroms, etc.
They know which system is superior...but they are unwilling to change their beliefs and re-examine their ideologies...therefore, they stew with anger at each American success.
