Apple and oranges...
ok, bear with me on this one..........
Evidence for a better life in Poland:-
1/ Better weather
As a Polish living in the UK - I miss a real winter. On the other hand - I am very happy that it is impossible to freeze my ass here.
2/ More emphasis on good food
Really? British love to talk about food, talk about food. The bookshops is full of cooking books. TV - don't get me started. I can not imagine any more emphasis to be put on the subject of good food. British are food-crazy!
3/ Diverse and rich natural scenery in Poland
Also diverse and rich scenery in the UK. Scenery full of history. But to see it - You would have to leave your London suburb and open you eyes.
4/ A more comprehensive tourism infrastructure
I beg to differ.
5/ More culturally engaged than in the UK i.e. free city centre concerts, kaberets etc
Take London for example: dozens of museums, galleries, concert halls. Hundreds of theatres. Vibrant stand-up comedy circles. But if your idea of "culture" is sipping beer during open-air pop concert - then you are right.
Of course, wages are higher in the UK but at what cost ?
At a very affordable cost.
This comparison is really silly and close-minded. If you take Poland as a "gold standard" of life quality, then you are right - every other country less Polish than Poland... I see that in your mind "less Polish" equals to "worse".
