Very often I hear that social democracies particularly in Europe have only risen due to the bourgeoisie's looming fear that if they hadn't implemented a few programs or policies to appease the working class peoples there would have been a communist revolution.

Now, this does sound like common sense. But is there any particular source that gives evidence to this claim? I'd rather be able to take a strong stance with this opinion by being able to cite sources instead of my friends' opinions.

Lenin writes that did not have the material to deal this question of affiliating or not with Labour.

Does he write about it elsewhere?
