Capitalism in European and American hisatory

Okay, I have several questions:

  1. Is there any source, maybe linked to in this thread itself, that explains why, although Scandinavian socialism is a myth, their welfare programs can be demonstrated to be failures?

  2. Although historian Tom Woods says there weren’t any net tax cuts under the Reagan administration, the '80s were more prosperous than previous decades. Why?

  3. The stock market crashed on October 29, 1929. Were the administrations of Harding and Coolidge as significantly (in comparison with their comporaries) pro-market as Woods implies?

  4. Evangelist Sam Gipp (while saying America got its prosperity by God’s blessing) says “numerous European countries have tried free enterprise and have not excelled.” I think this is ridiculous, but I would like to know if anyone knows where he got this idea.
