Do you think no other countries bring foreign workers for cheap because the locals won't accept the job at the wages paid?

Canada does it, the US does it. No EU needed for that.

The alternative is to have production stalled or unaffordable because you don't have enough people to do the grunt work.

The industry jobs are more likely to be offshored without free movement of people, because import taxes are cheaper than manufacturing in high-wage countries. That's why free movement of goods and people go together.
