I would point you to a recent Lemmy post that shows grocery and processor profits spiking, while farm income is flat.

Cancelling the TFW program would help, sure, but the other half of the coin should be much, much higher marginal tax rates that put a brake on profiteering. One of the reason everything is so theadbare is because the rich are taking an increasing share of the wealth, and the reason they're doing that is because we don't tax them for it. Because we don't tax them, they have no incentive to invest in people or productivity improvements, and every incentive to use those profits for financialization.

I think this reply may be a part of the problem with this debate. It assumes that the participants in the program are agricultural workers. This is traditionally true, but under the current program agriculture workers only represent 60%.

An estimated 15% work in food service, with another 10% in the broader hospitality sector. 5-10% work in construction.

The old adage is "you don't have a labour shortage, you have a wage shortage", and it's true here. If we had a labour shortage, companies could pay more and/or train people, but that would be expensive. Better to just strip-mine south Asians for every cent they're worth.
