It is interesting how receiving the greatest benefit for the lowest cost is considered pathological, yet also the entire basis for our economic system.

What I read from GP's comment was not that this was the tradeoff, it was that people who pay less than market value tend to be the most troublesome customers. I can tell you that holds true in any market I've ever consulted for or have used myself. B2B transactions tend to be much smoother than a visit to Popeye's on the average.
