(1) The dignity of the human person (all human beings from the moment of conception to the moment of natural death have inalienable rights that no government may infringe).
(2) The preferential option for the poor (all other things being equal, and all justice being fulfilled, if a policy can help the poor or disadvantaged it should be implemented).
(3) The principle of subsidiarity (the more locally a decision can be made the better, with the family being the optimal locus of decision making).
Pretty much every social policy of the Democrats immediately and blatantly violates principles (1) and (3) and usually violates (2) more subtly.
If only...
If only the honest poor and disadvantaged could be separated from the huge army of indolent and opportunistic parasites which comprise the US culture of social and economic parasites.
