Then you have a failed business model.

The solution is not to screw your workers, but to make your business better so you can afford to recruit and hire the best and brightest while still earning a profit.

If you can't earn a profit while operating ethically, then you need to get out of the tomato growing business. If demand for your product is not enough that you can raise your prices, then the market is over-saturated and you offer nothing unique to the customer.

If your model only succeeds because you exploit labor and pay them like slavery, then you are destined to go the way of the confederacy. It is not the responsibility of labor to support your failed business ideas by sacrificing a living wage.

It is the responsibility of the business owner to make ethical business decisions to protect not only profit, but the welfare of those in his employ.

You seem to believe that the quest for profit to benefit only the owner or shareholders trumps the rights of workers. That's where you're wrong.
