It's easy to account for it. One business that's paying has determined it's worth a certain amount and another that determined a different amount. Never said there was a standard that Job A is worth amount B. The standard is determined by the one doing the paying which means the amount can vary based on the one making the decision..
YOU DID SAY THERE WAS A STANDARD.
You've said it several times.
You said a $5/hr job is worth $5/hr.
Now you're being tested because you're realizing that no standard actually exists.
What a phony. I caught you in your own flawed rhetoric.
PS: everyone in your life is laughing at you.
