GLA, Robert Mac has it right.

In a true free market economy, when you want more workers than what you are getting, you pay more and or make the conditions of work better.

Packers have been suppressing wages via immigrant workers and decreasing the working conditions.  They can decrease the working conditions of illegal immigrants easier because the illegals have little choice and fear the retribution against them.  That is why packers have hired them.

Just like the BSE fiasco, packers should have to pay for BSE damages and they should have to pay for illegal immigrant worker costs when they actively promote them from other countries.  Why should the public let them off the hook and pay for these problems out of taxpayer  or producer money?
