If we understand Liberalism to be a social philosophy tradition starting with Hobbes, being further developed in various forms through Locke, Rousseau, Adam Smith, Edmund Burke, John Rawls, etc. and seeking the liberation of the individual from culture, community, and family then for various the social Liberalism of the democrats (which seeks particularly to liberate people sexually from community judgments and rules) is closely connected to the efforts by the GOP to do the same for people in the business area. They are based on a common view of what it means to be human, a particular view of what freedom is, and so forth.
These assumptions are not really so fundamentally shared outside North America. So in both Sweden and Denmark, society looks a lot more like it did structurally to Aristotle than to Hobbes -- strong family households joining together in local communities to address common issues. Those local communities joining together into larger and larger units to address common needs until you have the overall kingdom. These places are less individualist and more localist.
Growing up in small towns in the US, I can also tell you that this Business Liberalism is most heavily a force politically in the urban centers of the GOP. Rural politicians don't tend to push it in the same way.
