I live in Sweden and even looked it up and couldn’t find any information about free housing. Merely asking where they got that info from

Well, Sweden has the highest wealth inequality in Europe due to several billionaire families active in industry, they have a lot of influence on politicians

Except they’re not socialist

There’s no free basic housing in Sweden? Source?

Just because Sweden has a strong welfare system doesn’t make it socialist. It’s incredibly capitalistic with a high number of billionaires per capita, hence it ranks first for wealth inequality in Europe
