Pies and apples
In Dumb Metaphor Friday: "Growing the Pie", the author argues that the "growing the pie" metaphor is a poor one for conservatives and tries to come up with a more accurate one:
The conservatives would be much better off chosing something that actually expands. Say, apples. They want to grow more apples—which can then be baked into delicious apple pie. Except... if you want a successful orchard, you’ll ensure that your apple trees all have sufficient access to light and water. Taking decent care of your trees is the best way to get more apples. If you plant 99% of your trees in a corner of your orchard and give the remaining trees all the remaining space, you’re making terrible use of your resources. If you treat your trees equitably, you will get a better yield. Bigger pies.
I guess the problem I have with this is that this really doesn't represent the viewpoint of most conservatives (I hope). Using metaphors to describe real-life phenomena becomes a silly exercise after a while, but I'd at least like to try to extend the above metaphor to a liberal worldview. In a liberal orchard, you'd have the trees distributed evenly such that each tree receives equal resources (so far, so good). But now consider that plants don't grow exactly the same when given the same resources, due to genetic differences, and differences in the environment that you can't control (such as nutrients in the soil). Perhaps some get diseased. Now, the gardner might conclude, "That's unfair!" and proceed to give extra water, fertilization, and care to the less fortunate trees which are struggling to grow. That's great, but now resources have been taken away from the stronger, healthier trees, and I'm fairly certain the overall crop will be significantly diminished with this sort of gardening approach.
In conclusion, I agree that everyone should be given equal opportunities. And that there shouldn't be certain people given privileges above everyone else. But once people start succeeding, I don't believe some of that success should be involuntarily stripped away from them so that less successful people can share it. It sounds harsh, but in my opinion that's the closest to 'fair' we can actually get.
