There are lots of technical jobs in Europe, but many people are trained in the wrong fields. One of my nephews with a masters degree in business, retrained as an electrician and is now making lots of money installing A/C units in shops. Another nephew retrained as a gas turbine pump mechanic and now does very well with a gas distribution company.
What is wrong with being nationalistic? The EU is a very loose federation of nation states, each with its own defense force, police etc and the states on the periphery are responsible for gaurding the external borders. Spain, Hungary, Poland, Bulgaria, Greece etc all have huge border fences that put the old Iron Curtain to shame.
I used to say to the poor lady at the Telus call center: Please f'ing transfer me to a f'ing higher level f'ing technician who can f'ing fix my f'ing DSL problem. It worked.
You unwittingly mentioned the solution. Phone response systems listen for swear words and will transfer you to a human soothsayer if it detects profuse swearing.
