Warsaw can cut the love for Poland clean out of a person.
totally. Anyway, there are less now for two reasons, but the main one is that the dollar isnt what it used to be (and many teachers would take what little savings they had here and live the high life) plus wages for teaching used to be really good. Now, prices have risen noticeably but wages haven't gone up to keep up with prices.
The other reason is the EU, much easier for Brits to come over so there are more of them proportionately. For Americans it often isn't worth the red tape. I used to know teachers from the US that would come over on tourist visas and teach and no one would care, now the border patrol has wisened up.
