when we added socialist elements to capitalism (eg. social security, free healthcare, free education and so on) it didnt stop being capitalism.
This is a very black and white view of things, though. Norway is seen as capitalist, yet 2/3rds of Norway's GDP is driven by its public sector, the government owns 30% of the domestic stock market, they have a massive government wealth fund that makes returns in hundreds of billions of dollars annually which they could singlehandedly fund UBI with, they apply Georgist taxes to natural resources (oil, hydro, aquafarms) to collectivize profits made off public land, 60% union density, 20% of housing is collectively owned (housing coops)...
Like, at what point do we call a country "socialist"?
(Not to call the US socialist, but Bidenomics might lean like 1% in that direction, and that's my point - it's going in a socialist direction if very slowly, and if we can maintain it)
