Gallup Poll Assesses Views of Young Americans: one of the questions was "Thinking about economic issues, would you say your views on economic issues are -- [very conservative, conservative, moderate, liberal (or) very liberal]?", and the discussion of the poll says,

young Americans are considerably more likely to say they are economically liberal than Americans aged 30 and older are.

But what do people understand by "economically liberal"?

Jonathan Dolhenty writes that in the early nineteenth century,

an economic liberal supported the free market and opposed government regulation of trade.

So I guess "economically liberal" now no longer means that, but the opposite?
