Education, welfare, healthcare; not social issues? How so?
Very briefly, fiscal issues are those that revolve around what services the government should provide and how they should be payed for. Social issues revolve around what freedoms individuals should be allowed, and what role the government should have in enforcing morality (and what morals they should enforce).
So welfare, education and healthcare are all fiscal issues, because they're a matter of what services the government should provide, while gay marriage, gun control, abortion, etc. are social issues, because they involve the freedoms of individuals and whether or not to enforce a specific morality.
There is of course some gray areas, but that's always how I've seen the issues break down.
Libertarians, like Ron Paul, are generally socially liberal and fiscally conservative.
There are also some inconsistencies in how the major parties break down - while Democrats are generally socially and fiscally liberal, and Republicans are the opposite, both take stances on some issues that are opposite of how they normally view other issues. For instance, many liberals are anti-gun, despite that being a socially conservative position, while most conservatives take the exact opposite view, despite it technically being a socially liberal position.
