More immigration will certainly help the countries like Venezuela, whose citizens can simply escape to better places.

But at the same time, it will be bad for the host countries whose social safety nets will be strained and whose citizens will now have to put up with masses with vastly different values. And the interaction will not always be pleasant (eg. Cologne incident in Germany earlier this year).

So my question to you is - why do you think its a better solution to improve condition of some societies at the expense of some other societies?
