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.
Nobody wants to breathe dirty air or drink dirty water. But, if either becomes 98 percent pure, 99 percent pure or 99.9 percent pure, there is some point beyond which the costs skyrocket and the benefits become meager or non-existent.
If the slightest trace of any impurity were fatal, the human race would have become extinct thousands of years ago.
Not only does the body have defenses to neutralize small amounts of some impurities, some things that are dangerous, or even fatal, in substantial amounts can become harmless or even beneficial in extremely minute amounts, arsenic being one example. As an old adage put it: "It is the dose that makes the poison."
In other words, removing arsenic from our drinking water should obviously be a very high priority -- but not after we have gotten it down to some extremely minute trace. There is never going to be 100 percent clean water or air and, the closer we get to that, the more costly it is to remove extremely minute traces of anything. But none of this matters to those who see ever higher standards of "clean water" or "clean air" as a Good Thing.
One of the things that have ruined our economy is the notion that both Democrats and Republicans in Washington pushed for years, that a higher rate of home ownership is a Good Thing.
There is no question that there are benefits to home ownership. And there should be no question that there are costs as well. But costs get lost in the shuffle.
Among the things that Washington politicians of both parties did for years was come up with more and more laws, rules and pressures on private lenders to lower the qualifications standards required for people to get a mortgage to buy a home.
