It isn’t necessarily, but it’s currently used in the US to allow the wealthy to avoid investing in Americans.
Instead of investing in Americans by lowering costs of necessities (food, housing, education, children) they chase short term profits for the benefits of shareholders (which is by and large the ultra rich). It’s much cheaper to import labor where the above costs were paid for by somebody else.
> It's inscribed on a plaque at the base of the Statue of Liberty and is taught in civics classes as a representation of American values
It was created by an activist looking to further Jewish and Georgian causes in the late 19th century. Id argue she wasn’t pushing for American causes and sought to redefine them to include her groups.
> The idea is that, when you live in a society, you build upon a set of shared values and stories so that you can have something in common with your neighbor and something bigger than yourself to strive for.
This is a relatively new idea (the inscription you described above came after the Statue of Liberty). Civic nationalism does not work with the entire world as opposed to immigrants of European descent, as they do not generally share the individualist egalitarian mindset that is unique to the west. There’s ample evidence of this in the US, but the conversation usually devolves into racism accusations at that point.
