You’re right it is not fair if that crossover occurs but keep in mind that the system hooks into international agreements the US has made and it’s not as if they can be overhauled for the little guy/gal.
You can keep doing this back and forth forever as you have time, ratcheting up both variables forever and always assuring any concerned citizens that your goal isn't "really" to just make the variables go up and steal from them, it's just "international agreements" force your hand.
Nobody should fall for this.
