Sure, but how much of your wage do you spend buying electronics? The vast majority of my salary goes to fixed expenses like housing, food, healthcare, energy, and transport. Those are all highly location-dependent.
In location A you might spend 80% of your salary on fixed expenses, whereas in location B you only need to spend 20% of that same salary to pay for those expenses - leaving you with far more money for discretionary spending.
For sure, but that doesn't justify doing that per country. If you live in SF you could be spending 80% on fixed expenses, but I'm sure that in the US there are places where you could be spending 20%. This applies to other countries as well.
