This is an intense topic. I started doing a little research and found a few facts here related to transplant centers:
Though American transplant centers can list foreigners, they can make up no more than 5% of any center’s list. Most of non–U.S. citizens listed have substantial financial resources and pay in cash.
Some transplant programs will admit illegal aliens, but most are children. Some transplant centers have caused controversy by refusing to retransplant illegal aliens whose initial organs, received at the same hospital during childhood, have failed.
I would like to look further into what other countries are doing to improve and increase organ donation/management within their own systems. I can only imagine that is where the key to limiting out of country transplantations is going to occur.
Going to keep reading and pondering this one.
