Sort of like how the 'slight benefit' of allowing the most capable blacks to go work in predominantly white companies had disastrous effects on blacks?

Also, I'm not arguing that H-1B should be restricted to only the most capable members of a nation's society. I am super into allowing the least capable members of India to work in the US - for instance programmers who would only command $20K per year in the US job market because they are not very capable.
