I smell a rat.
There is no rat. The advice given toTommyG by Delph was sound, small town with no competition, people that are willing to help, rather than criticise. If you want to live in one of the larger cities then be prepared for a lot of competition. I have no idea what money he is earning, but, if, he can make a better life here than in the UK, fair play to him. You hint as to if he is cheating the students he teaches which is strange, at least he IS an English native speaker, who has to pass some sort of criteria to fulfil the demands of his clients. He would not survive long by being a chancer,
From my experience, you have to fit into Poland, not, expect Poland to work around you.
I hope TommyG succeeds, and, maybe he can go on to advise/help others to persue their dreams here. I can think of many worse places to live and I think that our sense of well being is due to come under a lot of scrutiny very soon. The world is changing quickly, and not for the better.
