Good points from Thomas Sowell:
Life has many good things. The problem is that most of these good things can be gotten only by sacrificing other good things. We all recognize this in our daily lives. It is only in politics that this simple, common sense fact is routinely ignored.
In politics, there are not simply good things but some special Good Things -- with a capital G and capital T -- which are considered always better to have more of.
Many of the things advocated by environmental extremists, for example, are things that most of us might think of as good things. But, in politics, they become Good Things whose repercussions and costs are brushed aside as unworthy considerations.
