Throughout the history of mankind, we've always had the rich, and we've always had the poor. What makes America different, what makes her special, is we have a third economic tier called the "middle class". Only liberty and capitalism give you this middle class. No other system of economics (capitalism) & government (representative republic) combine to do so. This combination creates this robust middle tier and allows all to move upward based on individual effort and drive. This system promotes innovation and betterment for all.
And this is exactly why we must stay true to the founders of our country and not follow the ways of our current president who sells us utopia but whose policies are moving us back to the world of a few rich, many poor and none in-between.
The pitch of utopia — perfection in government, in justice, in economics, in opportunity — is usually well meaning but to achieve such goals in an imperfect world, with imperfect people, means government must grow large and liberty and opportunity must decrease. All become equal (in suffering and pain and dispair) while others are more equal (those who control the system and promise the world will be better if they control it just a little bit more).
It is interesting that Karl Marx never had a term for the middle class. He gave us the term "proletariat" for the poor, working class and "bourgeoisie" for the rich and aristocracy. But the middle class was a foreign concept to Marx. It didn't exist in his 1848 world, or not enough in strength to influence his thinking. And yet it is the middle class and the ability to improve one's lot in life which precisely describes the American experience of the last century. Consequently the first step to convert our county into a socialist nation is to destroy the middle class. Marxism only works when there are two classes of people, not three. Growing government and its control over the economy, and thus the lives of its citizens, is a crucial step in destroying the middle class.
Therefore be on guard. Watch for the politicians that describe social or economic justice through introducing new government programs or controls — taking more from the producers to give to the non-producers. We must stand strong against them and remove them from office at the ballot box.
