That pretty much applies to whoever controls government at the time, not just socialists. How it is used is more the question between socialists and other social/economic philosophies than the taking of it.
There's plenty of truth in that. However, IMO, the tradition of individual freedom that is the basis for the founding of our country does not include a central government controlling and regulating private wealth. Socialism, OTOH, by definition most certainly does do this in its milder forms, taken to its logical end, socialism does not even allow private wealth.
So I think it pretty clear that conservative views of taxes differ significantly from leftist. Or should.
