Really? Well, let's look at the definition of "nominal":
Nominal (adjective)
- Being in name only; not literally.
- To be related to something, without being literally something.
- Of an amount smaller than is expected.
Sources; dictionary.com, Cambridge Dictionary, Merriam-Webster.
Let's look at how the Nordic countries are described:
The Nordic Model:
"Includes a comprehensive welfare state and multi-level collective bargaining based on the economic foundations of social corporatism, and a commitment to private ownership within a market-based mixed economy."
Mixed Economy:
"A mixed economy is an economic system that includes both elements associated with capitalism, and with socialism."
Source; Wikipedia.
So, either you're wrong because you're saying the Nordic countries have no socialism, or you're wrong because you don't understand the meaning of "nominal".
