GPD is a system used to measure service and goods over a specific amount of time. For example if I’m buying programs from china for six months. GPD will determine if you have a greater investment in products or loss money in products .

Be surprised me because the US has a lower population rate the most countries, but has a higher GPD rate than the more populated countries.
The US is one of the top top leading countries when it comes to GPD
I believe business should not change some of their practices when it comes to new countries because they’re giving other countries some job opportunities. I believe local customs come in to play when importing an exporting to make sure there is no illegal actions going on. 
I do believe there should be lots of rules when it comes to international trade because, It will prevent illegal activity as well as mistreatment of workers. The rules in international trade should allow for businesses to create better opportunities. There should be laws concerning where the products and how they were obtained or created and the work conditions from where the product came.
