 if I say, hey, we're having a good year, let's replace some computers, let's replace some of this other stuff that we've been waiting to replace, I get to take those costs that year against the profits that year. And imagine how this works in the average workplace, where you say, why doesn't the boss replace this truck or that piece of equipment and make us faster and more effective at what we do? And you say, well, today he can take the whole write-off this year. In the future, he may have to write that off over three years or five years or longer.
