Last time I visited the US, I spent some time finding out about the history of the Catholic Churches in the US. Historically, the Catholic Church is the institution - not the US government - that provided an efficient "welfare system" to the Irish ( free schooling, apprenticenship for masses of poor irish).
Asians also have had the equivalent.
Roughly the same situation in some European countries; For instance, in France, the Italians were heavily discriminated against and the Catholic church provided the massive "welfare"; the Polish immigration had the "welfare" from the Communist party. The African ( mostly North African) got the "wahhabi" "walfare" with the disastrous consequences we all know of.
