You can't blame NZ for letting in some rich people as a risk/reward calculation. Presumably they will buy things and pay big taxes: a net benefit?
Identity politics is alive and well in NZ as much as it is anywhere. Blame the politicians who were in power 5 years back.
So you can't really call it an aspiration when all major political parties here support the same model - only the lens of folks political affiliations is being covered here.
