This statement is questionable, at least outside China. The misery being experienced by the persecuted has to be taken into account. There are more immigrants on the move now than ever before, and genocides happening all round the world. Even the poor in the developed countries would disagree with your statement. Their voice is rarely heard and media is busy shutting down all modes of communication they / we might use. Also the rocket technology you claim we have existed in the 70s 80s, but not so much now. Boeing and Space X and NASA between them have astronauts stranded on ISS pending commercial developments on ground, thus jeapordising both the ISS and all astronauts on it.
That would have been unthinkable in the 70s 80s.
