What Taks means is a proportionally higher degree of redistribution, but that doesn't sound very catchy.
Government does not own the means of production, nor does it limit personal liberty, unless you include taxes in that definition, and we live in market driven economies. The term socialist is used more as derogative to describe this expectation that government will provide in certain situations.
To find countries that would actually describe themselves as socialist one would have to turn to Cuba or Venezuela.
