You do realise that, for A LOT of the countries, our NMW is an absolute fortune?
You definitely can raise a family on it on some immigrants standards, by getting a house in a shitty neighbourhood that nobody here would touch, doing it up yourself, being completely nonplussed about siblings sharing bedrooms, having maybe one second hand work car, cooking from scratch as a default, only buying absolute essentials in thrift stores and restricting your entertainment to TV, religion and visiting your cousins.
The plus side is that you don't get killed/maimed/abducted/tortured, you are allowed to keep on working without having to pay racket, your kids actually have access to schools and GPs (as much as anyone here, but still way more than back home), your daughters don't end up being the local warlords brothel installments, your sons don't end up dying as a security to the same sum and you have a massive social standing in your home village for sending the leftover money - which can go a VERY long way there.
