The reality is...... MONEY! Generally, the more money a person has for discretionary spending, the more they will spend.
The more money a business makes, the nicer(more expensive) equipment they invest in.
Drive down a wealthy neighborhood and notice the cars you will see parked in the garages or porticos. People who own million dollar homes, drive expensive cars and have expensive toys. Recently I noticed A Mercedes Sprinter van painted in Amazon Prime livery. You don’t see many Sprinter vans used for delivery vans in the U.S. But if your company is Amazon, you can buy the “best”.
Human Nature! If you can afford the best, you want the best, you will buy the best!
