Chapterz people aren't fleeing the Nordic and British states as they're not socialist states. We live in a market economy and parliamentary democracy with a nominal royal head of state. It is very different to a socialist state - the state only controls the markets at the margins (ethics, taxes, health and safety, anti trust), we have an independent judiciary, independent media, a formal role for the recognised opposition and all members of the government are elected. European countries happened to have historically accepted paying a higher level of taxes in return for a safety net of services for all - most notably in health, maternity, unemployment benefits and income support. And we have accepted gun control in return for lower levels of homicide. From a European perspective these are all seen as a good social contract to a greater or lesser extent. Within each there are debates about big or small state, levels of taxes and safety v. civil liberties.
Cuba placed universal rights to work, health and housing above civil liberties - freedom of speech, to contested elections and meritocratic public appointments - as many socialist states do.
And Venezuela is its own special political and social disaster. To quote the BBC on Venezuela:
'Opposition lawmakers have been barred from standing for office, some have been arrested and others have gone into exile. The United Nations has accused the government of using a strategy of instilling fear in its population to retain power.
The South American country has been caught in a downward spiral for years with growing political discontent further fuelled by skyrocketing hyperinflation, power cuts and shortages of food and medicine.
Close to five million Venezuelans have left the country in recent years.'
