My own two cents, but since they're Eurocents

are they worth a little more ?

You all speak about multiculturality, yet forget who it was that colonized your lands (never mind the issue of the North American Indian)
Was it poor glebes, toling the soil? In part.
For the major part, it was a mix of :
1) people sentenced to exile (so it was in His Majesty's Courts, to populate the Colonies, including Australia, South Africa and New Zealand)
2) entire communities deported (see the Irish or the Scots)
3) families following their loved ones into exile
4) communities seeking freedom of religion (the Pilgrim Fathers, for starters, not to mention Russian and Polish Jews)
5) communities seeking freedom of identity (wars in Europe meant borders would come and go, up until 1946, see the Poles, the Armenians, French and German Alsatians)
6) servicemen (meaning, entire regiments) posted to the Colonies, and families would either follow or form
7) and, last but not least, farmers tired of toiling the soil for His Highness or His Holiness, and spent small fortunes for tickets to the New World.
Read any short story which describes Ellis Island, very few were actually escaping "famine", most could read and write and had money to spare.
Now, my own personal experience.
I went over in 1968, one of the first words I learned was "WOP", if I didn't answer whomever of the schoolkids called me WOP I would get beaten more or less badly.
I learned to run fast, verry fast, very quickly.
I also learned to read and write in English, and so they found a new reason to beat me up, I would consistently win the spelling bees, which to the eyes of many WASPs was unacceptable.
My perception is that America created its own identity out of the desire for one, but never had the years and years (centuries upon centuries) to allow it to sink its roots deep into the weave of society.
The result is a number of contradictions on the one hand and misconceptions on the other.
Elvis would sing of his "Yiddishe Mommye" and many of his fans would don the hoods of the KKK;
Some will brag of being "American as Apple Pie", which is the most notorious Bavarian dessert;
Cowboy songs are riddled with slow yodels (again, from Bavaria and Tyrol)
or will sing about
OR
Now, let me telly you abot what a "melting pot" really is.
It's NOT a soup pot, where you put in many different things, and hopefully all will cooperate to make the main ingredient (water) a little more tasty.
Because if this were true, then the fundamental ingredient, the WASP community, is defining itself as "insipid".
The melting pot, the real melting pot, is known in English as a CRUCIBLE, or by Alchemists and Esoterists as the ATHANOR.

CRUCIBLE TO MAKE STEEL

ALCHEMICAL ATHANOR

ESOTERIC ATHANOR.
So, the crucible will take copper and tin, to make bronze; but both copper and tin will lose their identity as such.
Here I do not see anybody willing to meet others, neither in a crucible nor in an Athanòr.
Do not forget what it was like in the 19th Century for your own ancestors when they crossed the ocean.
One thing is social discipline, another is deculturalization.
