Not factually correct. Lots of the people that left the uk and Ireland were poor and went to the USA to build a new life for themselves.In no way am I answering for Deacs, Boboshante, although he's been absent from the Forums for a period of days now. But as Thread starter, historical background between Europe and the United States seems appropriate, based on your highlighted statement above.
Let's not forget that the founders of America were the outcasts of Europe. They were murderers, convicts, gangsters, low-life, criminals, you name it.
Europe got rid of its worst characters, and those same minded folk set up America and its constitutional laws-right to bear arms.
So, its understandable why Europe functions around the "English Bobby" concept of unarmed policing; while citizens of America are faced with whether to open carry or conceal carry weapons.
The criminals were sent to Australia another democratic civilised country like the USA but without the gun culture.
It's more about maintaining a status quo so that those that benefit from the sales of guns maintain their wealth.
