Article doesn't mention the pay once. No matter what you think about this issue, this is total trash journalism by the reporter Samuel Benson and Politico. No wonder people don't trust news sources.
The lack of mentioning that in a story about the economic impacts of this seems like a deliberate choice to garner more sympathy than "I want to pay people $2 an hour to work" might otherwise. (That is a made up number, I did not go dig up the relevant PA pay rates.)
That seems to cover it in the words of one of the farmers. I personally wouldn't consider the article too sympathetic to them.
