Everybody is checking a persons before they will give them keys to theirs house. It's natural and common. I'm just a bit suspicious, when somebody would like to improve my live, or sell me something what I don't need for free. As you read second link 45% from 91.000 was already in england working illegally "as tourists". Please let we don't miss the point, Visa Waiver Program is for turists, now you start speak openly that it's a fake and your target to promote VWP is illegal immigration and illegal work in States. Brits didn't got bigger income from tourism, they got it from legal workers with work permits. Be honorable man and say that you want to WVP be used as a door for illegal immigration for Poles because of Polish economy. I think that we need improve polish economy and after that everybody will be accepted as tourist. It's hard to believe in this tourism from Poland when average person gets around 400$ per month and cost of food and housing take 85% from it. It's sound for me like 4 nights in hotel here and hamburger from "dollar menu" as dinner. Help for Poland in economy instead of "immigration back door" sounds for me better.
