The person you replied to didn't seem to imply they were, but conversely asked why the US is performing as it is given its wealth compared to Norway.
Average salaries in the US are far higher than in Norway, and GDP per capita, so you would think the US could afford to do better on more metrics
I'll also note that many of the largest welfare reforms in Norway predate the oil wealth, with the largest chunk of the reforms towards the current welfare model being passed in 1966, a year before the first successful oil well in Norwegian sector.
Yet while some things are probably better in the US (average house sizes are larger, I think), as someone who grew up in Norway and has visited the US many times and enjoys being in the US as a visitor, and currently lives in the UK, the UK is as far towards "American conditions" I can stomach. Dysfunctional but at least still has somewhat functioning public services. Why can't the US even match UK public services? The US is certainly significantly richer than the UK.
"Amerikanske tilstander" - "American conditions" - is a term with decades of use in Norwegian politics to scare voters.
Even a lot of conservative voters have historically been worried about "American conditions" because it has a history of being seen as lacking - ironically given far higher levels of faith in the US - in Christian compassion, which has made it unpopular even far into the Norwegian right-wing (e.g. quite a few Norwegian welfare reforms were passed in the 1960s under a center-right government that included the four center-right and right-wing parties of the time)
