I'm not sure when "big government" became synonymous with socialism in the US.
Living in Sweden, considered a socialist country by many US commentators, i can note that we have:
* Full civil liberties (free speech, press, etc.)
* Free enterprise (easy to start a company, sensible regulations, etc.)
* Very little corruption (supposedly lower than the US)
* Freedom to invest, and freedom for foreign investors
* Protection of property
* Fair trials (well, unless they relate to intellectual property it would seem)
* High, but sensible, tax rates (It is very possible to get rich, even though the tax rates are rather high on an international level. We don't pay for health care, or college, so the taxes on employees aren't as bad as they look on paper)
Our political system is a social liberal one, not socialist. Socialism is a form of government, and not a measurement of government size. It's a matter of fundamental ideas on law and property, not a matter of taxation.
