Scandinavian model relies on competitive private enterprise to create wealth, combined with strong labor union collective bargaining, universal public services, and high consumption/income taxes that apply broadly across society.
DSA seeks to move past or dismantle the capitalist economic system, advocating for social, public, or worker ownership of the means of production.[1]
