I don’t want to be involved in that discussion, but I just want to keep you up-to-date.
Polish economy is doing well, but it’s still not resistant for world economy, so you can note some significant slow down there as well. That’s causing some unemployment as factories producing for the western Europe, which is in heavy crisis, have less orders etc. Some branches of industry are especially affected.
Apart of that: Recently some banks like Goldman Sachs and some Danish bank were playing with Polish currency trying to do something like they did with Icelandish money before. Polish economy is much stronger and our country is much bigger, but it’s still winded up the exchange rate and recently pound was much over 5 zÅ‚oty again. That’s encourages some people who went back to Poland not long ago to come back to Britain. And this time it may be even worse, as that will be people, who already were here, who have contacts, who speaks English, who have some British documents etc. It won’t be a big move compared to what you had before, but the workers would be much better than it was on average during the last wave of migration.
But, from the other hand I just read something about eastern Germans coming to work in Western Poland… So it’s all (i mean EC economy) goes better balanced, as SOME Brits are working in Germany as well. I think in some years that would be just one big work market and there will be no more this hard situations caused by inbalance.
So that’s what I can read from Polish media.
As for the credit crunch: it’s not Poles’ fault that there is a crisis. It’s all started in US and it came to Europe via UK due to your tight economical connections with America. Off course it would come here anyway, so it’s noone to blame except some greedy fat bankers, who are now enjoying happy live on tropical island on pension earned from interest from their quit-pay. 
. In fact real victims of the credit crunch are some economies who weren’t at all involved in this system, but still have to comply with it’s results, like Eastern Europe or, say, China.
But it’s true that a huge amount of Eastern Europeans in UK makes lives of Brits harder. It’s always better to have smaller amount of competitors on the market, isn’t it? But you can just ban them from working here, as you already allowed them to come here, and it’s a basic law thing that you can’t withdrawn some rights already gained from people. If you want to compete from common workmarket in EC you have to learn something from eastern europenians - they are on average much more mobile, much more flexible etc. If you can’t beat enemy your way, do what he’s doing, only better. For example I am really suprised, as I am reading this forum that there is so many threads on “Poles go home” style and I can’t see almost nothing about changing your career. UK Haulage industry is dying and even if you send all Eastern Europenians home I doubt there will be enaugh jobs for all British trucker for some time at least… But that’s off course my own opinion and I do not wanted to be involved in such discussion, so forget it.
THIS IS A VERSION OF MY POST FOR THESE STUBBORN ONES WHO WON’T ACCEPT ANY INFORMATION WHICH NOT FIT INTO THEIR THEORIES
I, a wee stupid Pole witch mustache and laptop on the dash, who works for 40p per day and who can’t drive up to British standards and crashes on average every second afternoon, who lives with 40 others in a 1 bed council flat and earning 5690 weekly in benefits only, which are in majority claimed for my guinea pig which I left back in Poland, would like to ask you to forgive me my sins. This is me, who caused Credit Crunch, Global Warming, recent Earthquakes in China and Britney Spears is also my fault. I really apologise. I won’t do that any more. 
Blaming the poles for what has happened here PATHETIC typically English logic .
