The average monthly wage in Ukraine was about $120 in September, the State Statistics Committee said on its Web site, compared with $738 in Poland.
btw Im following Ukraine elections and incidentally I found polish average monthly wage is almost twice higher than you referred. I dont know where you found these information. Other thing is that if you want to go for vacation you should saving your money long before you will do this. Personally I wouldnt go to US, for example Czech Republic or Slovakia looks much better, cheaper and I wouldnt be suspected for terrorism and other stuff. But if somebody really want to go to US, it is his problem.
Be honorable man and say that you want to WVP be used as a door for illegal immigration for Poles because of Polish economy.
No man it is just your phobia. Your problem is that you think about US as a heaven, and Poles though something like that maybe in communist period, but if you didnt notice it is over it isnt 1980 but almost 2005.
Btw Be honorable man and say that you arent American
