From wikipedia: "Allister Heath, deputy editor of the The Daily Telegraph, wrote that the book shows how the “remarkable work ethic” of Scandinavians has been eroded by large welfare states over time." (Of course, don't take wikipedia's word for it-- read the book yourself)
My take-away: Heavy socialism has absolutely stifled economic growth in Scandinavia. During the peak of welfare in Sweden, for example, net private sector job growth was ZERO.
If you want to stimulate economic activity, instead of giving everyone $10,000 per year, why don't we just cut taxes and removed red tape.
(I know that Scandinavia didn't technically have a basic income, but I still think that this material is completely relevant and very telling).
Edit: I said "During the peak of welfare in Sweden, for example, net public sector job growth was ZERO". I meant private sector. Major mistake, my apologies!
