Yes you're right. My country belongs to top 10 that has a big population all over the world. Every year there are thousands or million graduated in different courses but job opportinuties are not enough. With that, professionals have no choice but to go abroad because in abroad there are lot of jobs waiting plus big salary. So instead of professionals will help or can help the country, they are helping other country.
