The purchasing power parity of currency in country A is 4 times as country B. (https://en.wikipedia.org/wiki/Big_Mac_Index).

Now they are going to incorporate in country A. Which of the following arguments makes more sense to you?

Argument 1: The equity of the person in county A should be 4 times as person B because he/she had to work without salary in a much more expensive country and therefore has accepted much more risk.(Person A ignored a salary which was significantly more than person B.)

Argument 2: They both have same qualification therefore their time is worth equally regardless of the currency and cost of living.

I appreciate your feedback.
