No no no no no!! Do not repeal the Diversity Visa Lottery! It has a merit-based portion to it already (one of the main critiques of the opposition is that immigration should be merit-based...they're clearly ignorant of how the program works). A lot of people rely on it to escape terrible circumstances and have the opportunity to live a dignified life of opportunity. I work in education and have students who are in the US because of the lottery system, and they're graduating at the tops of their class. All of their contributions to our society will benefit the United States and not another country; I see that as a GOOD thing.
