Dems represent the weaker, less able, dependent residue of a free and successful society

There is nothing unique about the huge political chasm in the USA. It is natural among non authoritarian nations who prosper. You have the haves and the have nots. The doer's and the left behinds. Those who appreciate the independence of the individual spirit and those who lack the means, intellect or spirit to cope and compete. The USA's situation was complicated further by bringing huge numbers of backward laborers and manpower from all parts of the world here.

This all leads to a clash of wills at some point. To stall this clash the more industrious develop methods of some sharing to take care of the less endowed. Naturally political parties, and other fellowship groups (similar to gangs initially) form. Lead by those who see an opportunity to seize power and wealth. And fed by greed and the comforts of the haves and the desire to possess same by the have not. Manipulating and advocating. One side wanting to maintain and the other wanting to seize. And ultimately leading to clashes. Our situation has been complicated by unprecedented wealth and living standards created which inspires even more massive immigration of the lesser able and dependent. And the spinning off of labor, wealth and means to other nations.
