My simple question is why to people pay in the first place?
Because they can! They have the money, and they want to spend it! And that’s not the whole story! You made one wrong assumption:
Then i realized it comes down to people with money. They don’t care if they get taken a little advantage because it’s nothing for them.
They don’t get taken advantage. Instead, they feel privileged to be able to pay for premium services. It makes them different from the less wealthy. The same thing applies to everything: cars, clothes, houses, accessories. Sure, paying more promises better quality, but what you actually buy is exclusivity.
The worse part comes when the less wealthy want to show off the money they don’t have and opt to get in dept in order to obtain some of the premium products and services.
Still, the worst part comes when the rest, that don’t really need the excess, get “robbed” from some of their little joys (or big needs), just to satisfy the vanity of the “best”.
