No, they complain about Mexicans, instead!
(Although somebody, somewhere, is making a killing by running their factories with illegal labour, willing to work for less than the minimum wage and only going through the motions of complaining about them...)
As AOG pointed out, the big corporations don't care where you're born or what country you work in, so long as you can mutter enough words of the local lingo to serve customers, energetic enough to put in 40-50 hours per week and don't have a clue what your own labour is worth, locally, only that it is more than you can ever earn 'back home'.
Clearly, the EU is not just big business' friend, it was probably their big idea!
