We can refer at case that China represents, even though we need to take dumping into account, we can observe that multiplying the average wage by 300% in less than 10 years did not generate a sudden rise in the price of the products exported and sold on the shelves of western retail chains.
Forcing poorer countries to take a minimum wage set on a global scale could be catastrophic for that country. First off many families need the jobs, even though it has poor pay and work conditions. A minimum wage may force companies to lay off or go out of business. Many of those workers would agree that a bad job is better then no job. It would also hurt those countries because many businesses would leave. Why work out of a third world country when it costs the same to work out of a first world country. That would deprive the countries out of crucial economic resources. But that’s if it is even enforced. Many countries don’t have the resources or the want to enforce a global minimum wage. Many governments use these companies to their advantage. We very well can’t invade a nation on these terms and cutting off funding means more people will likely be hurt. In conclusion, after considering just a few of many reasons, A global minimum wage would be more harmful then helpful.
