I don't think this article from the DI had an expiration date:
Don’t confuse ‘social democracy’ and ‘democratic socialism’
By Austin Stadelman, Columnist
September 5, 2018
"Democratic socialism refers to the anti-capitalist philosophy that the public controls as the means of production through a planned economy. Resources and labor are distributed according to what the society, whether that be through means like state or planning committees, deems appropriate.
Social democracy, on the other hand, accepts the market principles of capitalism while emphasizing the importance of collective bargaining and unionization, regulatory overwatch and an adequate welfare system."
"This confusion in large part stems from Senator Sanders incorrectly identifying himself as a democratic socialist, to which he is not, as he is not even a member of the Democratic Socialists of America (DSA). He is an Independent whose beliefs align with those of a social democracy, showcased by his high praise for the Nordic model countries.
Yet since he self-describes as a democratic socialist, his supporters also inaccurately describe themselves, or at least the ideas, as democratically socialist. The actual philosophy of democratic socialism is based in an anti-capitalist planned economy. That is not how the Nordic model operates nor is it what Mr. Sanders endorses either, as they both support the free trade and the movement of goods based on liberal economic theory."
