They did, and many people made the argument that some prices are worth paying. I would rather pay a bit more for my strawberries than pay less and import cheap labour from abroad, house them like sardines in a shipping container, charge them half their wages for the privilege then sell them all their food from the on-site shop just so they can send a couple of quid back to their families. It's industrial, international exploitation and the middle classes having cheap strawberries isn't a price worth paying. Local people doing the job at good rates is what should be incentivised.
