That... goes just totally counter to my (admittedly limited) experience with the most impoverished people in Sweden: the Romanian Romani. They are not at all "[willing] to say good-bye to yesterday and move forward to new, unknown experiences", in fact the exact opposite. Part of what keeps them in extreme poverty is their cultural ideas of what it means to be Romani at at all.
I would state the exact opposite: poverty is when you CANNOT "say good-bye to yesterday" because you are desperately trying to fix the problems/debt of yesterday even if it creates new problems/debt for tomorrow, because the alternative is starvation.

They might not necessarily be from Romania. At least from my experience next door in Finland, it has been very common for the media to write about “beggars from Romania”, but if you actually chat with the Roma beggars on the street or the bottle-returners in front of you in the queue, often they come from Bulgaria instead. Yet for some reason Bulgaria never seems to get mentioned, perhaps due to the popular confusion of “Roma/Romani” and “Romania” even though the words are not actually historically related.
