Big agriculture is spoiled - they want workers who work for peanuts and don't complain about unsafe conditions.
Maybe if they paid a decent wage they could get the job done by U.S. citizens.
And yes, I'd pay more. I'd pay more to support American citizens.
Saw this in spades in the construction industry (when we had one). Houses were built by young skilled American men, citizens. Framing, roofing, electrical, plumbing. My friends often worked in construction - summer jobs too.
Then the illegal Mexicans started taking over - it got to be if you weren't Mexican you were locked out, pushed out. Yes, they worked for less. Quality is not as good now, for many reasons, not the Mexicans (who are certainly capable of good work) but the poor quality is related to the same reasons low-wage workers are hired - greed.
Saw this in the shrimping industry on the Gulf Coast too. My uncle was a shrimper back in the day.
Vietnamese took over. Worked for less, lived very poorly.
I was told the apple orchards in the Northwest were the same. Used to be young white folks, seasonal - made good money. Now Mexicans - work for less.
This is the 'surplus labor' that owners and bosses love. Thanks to a Congress that opened the gates to massive immigration, legal and illegal.
Can you guess why they did that?
