             | 
             | In the US, different people use "liberal" to mean:
             | 
             | (1) Everything to the left of center of institutional power
             | of the Republican Party, or
             | 
             | (2) Everything to the right of their preferred viewpoint
             | (common among the US's small number of actual leftists.)
             | 
             | (3) People who agree with their particular take on pro-
             | capitalist econonic policy (often prefixed with
             | "classical".)
             | 
             | Among other uses.

               | Well, for Europeans (and I'd guess Canadians, Latin

               | the fuzzy "border" part of that line, always to the right
               | of it.
               | 
               | Centrist is the more accurate term for Dems (and even
               | that's charitable).
               | 
               | It's basically center-right (Dems), and right-to-far-

               | 
               | Sure, for some Americans, Democrats might be called

               | within the bounds of the present system of capitalist
               | production, and has, therefore, no direct interest for us
               | socialists who want to do away with that system.
               | 
               | >Indirectly, however, it interests us inasmuch as we must
               | desire as the present system of production to develop and
               | expand as freely and as quickly as possible: because
               | along with it will develop also those economic phenomena
               | which are its necessary consequences, and which must
               | destroy the whole system: misery of the great mass of the
               | people, in consequence of overproduction. This
               | overproduction engendering either periodical gluts and
               | revulsions, accompanied by panic, or else a chronic
               | stagnation of trade; division of society into a small
               | class of large capitalist, and a large one of practically
               | hereditary wage-slaves, proletarians, who, while their
               | numbers increase constantly, are at the same time
               | constantly being superseded by new labor-saving
               | machinery; in short, society brought to a deadlock, out

               | remodeling of the economic structure which forms it

               | 
               | From this point of view, 40 years ago Marx pronounced, in

               | plan, and therefore the plan which would soonest bring
               | capitalist society to that deadlock. But if Marx declared
               | in favor of Free Trade on that ground, is that not a
               | reason for every supporter of the present order of
               | society to declare against Free Trade? If Free Trade is
               | stated to be revolutionary, must not all good citizens
               | vote for Protection as a conservative plan?
               | 
               | >If a country nowadays accepts Free Trade, it will
               | certainly not do so to please the socialists. It will do
               | so because Free trade has become a necessity for the
               | industrial capitalists. But if it should reject Free
               | Trade and stick to Protection, in order to cheat the
               | socialists out of the expected social catastrophe, that
               | will not hurt the prospects of socialism in the least.
               | Protection is a plan for artificially manufacturing
