Same kind of deal with most any refuge situation though. Country gets into a war for whatever reason, some crazy person gets in power and decides X group is undesirable, natural disaster levels a town, someone has to foot the bill but just passing it off to whatever location they land at won’t work. Within the USA we have things like FEMA that could help out by pooling resources from multiple places to support an affected region, but that becomes a lot more difficult when you’re talking international. We can’t exactly demand taxes from someplace else entirely to fix the issue, and even if we have local resources it’s going to detract from supporting the local people that already need help.
It’s stupid and largely the fault of a profit driven mindset by society. We have housing in abundance that nobody can afford and piles of food thrown out at the end of the workday in restaurants and cafes because they’re not allowed to give it away (supposedly for health reasons but if it was good enough to sell before closing time it’s good enough after).
