Labor mobility. In markets, supply is represented by companies while demand is represented by customers. Its not the demand of the product that pays, it is the skill set of the employees that determines the their degree of pay. If you ask yourself why a retail sales person is paid less than a doctor, you will obviously note that the difference in their pay is their skill. Businesses look for profits, and skilled workers drive profitability high hence they get to be paid more than low skilled workers.
The League of Nations was established after WW1 to keep peace. There is currently a “United Nations” there goal is to promote peace and prevent war through diplomacy, just as the League of Nations.
Now whether or not you believe the concept of a League of Nations is good or bad is up to you, i hope this helped! :)
