Because you make your money through hidden fees

Your employers charge a small fee for their services, or even offer their services for free.

Where they really make their money is through hidden fees.

They disguise their fees so that their customers don’t know what they’re paying.

For example, they offer zero-fee currency exchange but hide a $20 charge in their adverse exchange rate.

You know that these hidden fees pay your salary.

You also know that disguising these fees is dishonesty not far short of fraud.

This is not what you were meant to do in the world.
