If anyone has any ideas on how I can get this pesal thing or at least rent a house/apartment
I do not understand why you can not get an apartment or a house?. Renting a place is done through private people. Of course it depends, in Krakow the students take all available places and the best time to get a place is mid summer.
Of course I agree with what you are saying but I have lived further east in another "EU" country and it was a million times worse (if you can believe that) so for me coming to Poland was like a breath of fresh air, returning to the "west" and everything was in colour, I had to leave the other county or else I would have gone bananas, I hated it but in fairness to you, you do not sound like you hate it here (excluding the buearocracy).
I have not got a Pesel Number, my passport number always works. Why do you need a PESEL number?
earn the equivalent of 15,000 pln
If you do not mind me asking, what do you work at to get that wage? and are there any jobs going?
The Poles that can change Poland are those in the more recent generations, at the same time its those same Poles that are coming to the UK, Ireland and the US.
For real change, I think, that these people will see what is happening in other countries come back to Poland, expect the same, not get it and change it and probably make a killing (big money) changing it.
