‘I’m fighting for my country’: anger over immigration spills into rage on Dublin streets

I genuinely want to know, I'm not against immigration. I support it. But what is the long term plan here. We're going to reach population maximum simply due to resources. Are third world countries just supposed to forever stay in third world crisis sending refugees to the first world countries? Are we not striving for the same equality world wide where every area can develop to a functioning first world society? We could retain everyone's diversity if crisis areas could retain their culture instead of destroying it for the sake of short term single generation profit.
