How did the 6 year old migrant kids choose to go to the US, to be separated from their parents and put into solitary confinement? > The west can always be more welcoming and there are ugly moments; but there is a vast reserve of people who look at western countries, think 'I want to migrate there, it is better than where I am' and act upon their thoughts.
