What's with all the hate towards socialism?

Is it any coincidence that the happiest countries in the world are the most socialized economically? This link: http://www.dailymail.co.uk/sciencetech/article-2696136/Why-people-Denmark-happy-Study-claims-Danish-DNA-king-pursuit-happiness.html  shows that Denmark, Norway, The Netherlands, Switzerland and Sweden are the five happiest countries. What it fails  to mention is that all of these countries have modeled their economy around socialistic values. This article http://www.dsausa.org/what_can_we_learn_from_denmark shows that socialism could fix what we believe to be ailing our country, so why don't we just do that? Under that same Google search, I found this webpage as well, http://www.teapartypatriots.org/news/lessons-better-left-in-denmark/ and while this does bring up some good points on how the system that is in place may not help Americans, we can easily model our economic policy towards the good points of socialism, such as the great free healthcare, or the free college education. This could dramatically help Americans, especially the newest generations. Feel free to comment what you think about this. Turns out that links don't work very well with this, so you will just have to right click+open webpage to view them.
