You appear to be disconnected from the real world, Kirkland. There are many illegal immigrants out here and they stay under the radar by working for cash and it does indeed bring wages down. In fact even a lot of legal immigrants do just that to stay under the radar as they should not be doing extra jobs as it violates their visa. As do locals too as they are naughty. I can order chicken and pay a couple of quid less if I just pay cash.....why is that? If somebody illegal and unqualified is willing to work for half, you don't think some corrupt business owner will sometimes be tempted to take that bait?
