So Thomas Sowell says it right. Trade-offs are a necessary part of life, political or otherwise. Remember that when you think "it sure would be nice if those mean developers would build the necessary infrastructure, but I also want them to build houses that cops and teachers can afford."
Well, which is it, young feller? Do you want I should build that road or do you want I should build inexpensive houses?
Money comes from somewhere, ladies and gentlemen, and it's almost always the end consumer that pays the costs associated with bringing a product, any product, to the market. Do you think gas taxes are paid by the producers of gas? Think again! Do you think import duties are paid by the importers? Think again! Ultimately, the consumer pays, because companies pass all their costs along to whomever the next consumer of those goods or services are.
So, I ask you, when you think something is an unalloyed good, who pays for it? We all do, in some form or another, be it higher prices, decreased mobility, decreased choice in the marketplace, whatever. Trade-offs are inevitible in life, and we shouldn't act, or even hope, like they aren't.
