The USD has been one of the best performing currencies in the world in most people's lifetimes. I'm sure that most people would prefer to be paid in that currency.

For every Swiss Franc that strengthened 15% against the dollar in 10 years there's an Argentine Peso that because 45 times weaker in that time period.

Not sure how the long term exchange rate movements are relevant for most people who take a paycheck, spend a great deal of it, then use the rest to pay down debt or invest. Not many people are choosing to long term hold and deciding between dollars or pesos. And even if paid in pesos you could open a dollar bank account anywhere.

If you get paid in Peso you lose money every payday that you don't get a significant raise in salary. If you get paid in Dollars your salary raises roughly on pace with inflation.
