Poverty in Europe is usually defined as having an income of less than some fraction of median income. For instance in Norway and the UK this is 60% of median disposable income. See https://en.wikipedia.org/wiki/Poverty_in_Norway and https://www.nourishcommunityfoodbank.org.uk/docs/The_definit....

That is, poverty is relative to the environment in which one finds oneself. And we should care if only because someone without a reliable car, a mobile capable of doing the things that need to be done like banking, tolerable accommodation, etc., eventually becomes a burden for the rest of us, disaffected, disenfranchised, unable to participate in society. And that goes double for their children.

And of course we should care because they are humans too.
