Consider that a linear equation actually gets less and less effective relative to itself. For example, increasing 100 to 110 is a larger net gain than increasing 500 to 510. It's the same case the other way around: decreasing 100 to 90 is a larger net loss than decreasing 500 to 490. It's a little hard to explain intuitively, but I hope that helps.
