The first point you’re wrong on, as I have explained.
No you haven’t. Bismark only implemented his policies to placate a working class as you yourself claim. You only need to placate and disarm a class if they become a threat to your power. Your examples only further reinforce my point that states in general have to be compelled to provide welfare policies. It takes some level of success in class conflict to win concessions.
Both proofs and indicators serve similar goals rhetorically, I don’t see the point of your distinction here. I also didn’t say “proof” when criticizing your point:
They do not at all. If you drank a soda that tasted sweet, that would be an indicator that it had fructose in it. But it would not be proof as the soda could have artificial sweetners like sacharine instead. The implementation of welfare policies are the result of an intermingling of factors, and each country has its own circumstances.
That is correct, however; both figuratively and literally.
So far, you have yet to explain how exactly the USSR under Stalin was not democratic, which was the whole thing I was mocking your views over.
