Clearly no Nordic country is a panacea. But the issues you mention are relevant to a whole bunch of northern European countries, many of which are pretty "socialist" by American standards.
On the oil question, Norway is in any case the international exception. Most countries with oil are not socialist paradises but rather repressive police states. Or semi-failed, like Venezuela. Even before the climate crisis made it unethical, oil was a decent predictor of bad social outcomes. Norway aside, the world's most successful countries, as measured by HDI rather than GDP, tend to have few natural resources. Or almost none at all, like Japan and Germany.
It irritates me that, even today, people keep mentioning oil as some kind of magic solution. It's the opposite and always has been.
Norway being the only exception.
