Czech economy is considerably stronger (per capita, of course), many Poles work in CR, prices are fairly equal but Czech wages are +-50 % higher. Unemployment 16 vs. 4 % in favor of CR. Few Czechs work abroad comparing to Poles, itīs partly because of higher livinf standard in CR and partly because Czechs are lazy and less enterprising than Poles.
We "dislike" each other just like other neighbors (Germans vs. French, Frecnh vs. Belgians and Brits...) but generally we are good friends :-)

Poland before Norway
... no way, man! Norway is the richest!
