Not all Poles are pleasant and well spoken, neither are thay all hard working.
Some are chancers looking to milk a system.
In appearance many are swarthy and unkempt.
Take a look at most building sites and they'll fit in perfectly
you can get away with Scruffy on a building site in a way that you cannot get away with in something such as window cleaning or carpet cleaning.
I don't mind the inteligent and articulate immigrants, they may well build solid businesses, they will pay their taxes and blend in well.
With window cleaning, for an immigrant of any non english speaking country to be successful he will need to be articulate, neat, presentable and persuasive.
How many are going to be that? Those that come over thinking an easy way to earn some money might be to buy a bucket and a ladder and become a window cleaner, but those are the ones that are going to find it hard to actually build a round of any real substance.
They will be more of a threat to those in the employed sector, whether window cleaning or otherwise.
Employers will be more than happy to take on these people (and exploit them too in many cases) and in that respect they are a threat to jobs.
Immigration in this country is frightening and out useless government is too scared to do anything about it, a whole host of problems are going to build up as a result is something isn't done about it.
Some will feel the bite (self employed window cleaners) but I don't think it will be as bad as many anticipate.
