Here we go again with confusing socialism with a welfare state. Socialism is government control of the economy in general, industries in particular, and, oh yes, every other aspect of peoples' lives. Socialist states ENCOURAGE abortion as it gets rid of people they consider "undesirable." What's more, they make it, in a manner of speaking, retroactive. Socialist (both fascist and communist) states have murdered over 100 million people in the 20th century, and it is still going on today.
Everybody likes to look at the welfare states of Europe as role models. OK, maybe they take care of people, but at a level of taxation we Americans wouldn't tolerate. And they have (mostly) free-market economies. The United States has taken on some aspects of the welfare state.
