Social democrats (aka, “liberals” or “progressives” in the USA) generally support the welfare state.
In so doing, they continuously seek out ways to promote government interventions into the economic & social lives of their fellow citizens. And they do so under the false presumption that they or operatives of the state can know what is best for the overall community.
In turn, they reveal much about their own inadequacies. They are too intelligent to try to defend socialism, but they are not well-informed enough to understand why they should defend economic freedom as a bulwark against government oppression.
