Not to be cold, or make light of this situation, but immgration is not the solution to the worlds problems, and in fact, it creates more problems. Typically the brightest and most capable people and potential leaders of a given nation in turmoil are the ones who migrate to 1st world countries. This means the people who can actually change their countries are leaving behind the people that are less likely and capable of changing.
I believe the entire 1st world could only manage around 5-10 million immigrants per years before everything destabilized. There are more births per years in countries where people are impoverished than can be taken away, not to to mention the BILLIONS of people left out. I mean, immigration AT best is like paying an interest only loan. It doesn’t make a dent into the huge principle and continues to get worse.
Here is a great video on it that is an eye opener.
