Question

What if US allows every blue collered worker immigration without visa?

Answer 1

Well, we kind of already do -- tens of millions of "blue collar workers without visas" have already crossed our southern border.  The results would be the same -- cheaper produce and construction on the one hand; billions spent in educating, incarcerating, medicating, immunizing them and their offspring on the other.  Plus the other crimes and problems that some of them have committed and created.  The problem is that elements on both the left and the right have a stake in continued illegal immigrantion, while the great majority of voiceless Americans in the middle are against it.

Answer 2

Blue collar workers are fine...as long as they don't belong to a Labor Union

Labor Unions are anti-American
