Lets say I have 100 people working for me picking 10 apples a day, at the end of the day I take 3 apples from each person. 3×100= 300 apples for me 🙂
Now lets say I hire 1000 people and they each pick 10 apples a day, at the end of the day I only take 1 apple from each person 1×1000= 1000 apples for me 🙂
As you can see the more people I have working for me means I have a bigger group that I can take from, which means I can cut down on the number of apples I take from each person.
Yet I end up with more apples for me at the end of the day.
