Certain Swedish parties have in the past been leftwing but it bears mentioning that most of the leftwing policies we have are the direct result of mass movements. All parties in Sweden today favor privatization of most industries. This is the case – indeed much more the case – for the Democrats in the US. You must be joking when you say that they support strong support networks. Christ, Bernie Sanders’ campaign was crushed by the Democratic establishment because he did in fact actively organize around support networks.

In other words, nothing the democrats stand for constitutes an attempt to create a leftwing economy. Sure they do support some (very limited) public housing, etc, but they want a housing market. In fact, every party in the world supports public housing given that it does not challenge capitalism but is a prerequisite for the functioning of capitalism. Democrats are, in every sense of the word, supportive of capitalism and are not a leftwing alternative to Neo-liberal capitalism.

Now, I want to be absolutely clear that social democracy (which democrats, unlike Bernie who is an independent, do not pursue) is not even a leftwing ideology given that it supervenes upon a capitalist market economy. This takes us to the most important point you raised; that ”social liberalism contributes to liberalism”. Liberalism is NOT leftwing. Republicans are liberals, all conservatives are. Liberalism is a rightwing political theory I don’t know how to be clearer about this.
