The youtube channel, Economics Explained, has a lot of great videos on macroeconomic concepts. They recently featured a video on Norway pointing out how it handles its economy near perfectly.

The video explains Norway got pretty lucky, and it's not like every country could straight up copy them and succeed, but the major points are:

1. Their massive natural resource reserves are majority owned by the government. The government puts the profits from this into stable long term investments to benfit the citizens of the country. In many other countries, natural resources have been sold to private companies for a one time payment and private shareholders now benefit from the long term investment.
2. Their government has one of the highest tax rates in the world, even though they earn so much profit from natural resources they could literally have a 0% tax rate. Despite this massive tax rate, Norway has some of the lowest emigration of people and companies. Nobody has fled the country due to high taxes like many fear would happen elsewhere.
3. Their government spends heavily on social welfare and ensuring a high quality of life for all of its citizens, and their companies provide short work weeks and long vacations, which are huge reasons why nobody has left.

I think when people say they hate capitalism, what they mean is they hate working 50 hour weeks at a job they hate for a boss who treats them like dirt for a salary that doesn't even pay their rent while the CEO has more wealth than small nations and spends it on eating endangered animals on their mega yatch with politicians and judges who then pass laws making it legal to hire children and dump garbage into the ocean. They don't really care about private companies and investments, they care about how sociopathic greed has become so normal that it's actively defended.
