I think for that sort of thing to work, you need passage to wherever to be affordable for the refugees, or at the very least, some means for them to work off the cost of it once they're there.

Which when you consider that Elon Musk has said the cost-per-person of his 'Mars Colony Transport System' prices out about $80k I think was the quote, once it's making regular round trips... that could work out. [refugees from Syria and China pay that much to the criminal gangs to get to Europe.]

Still think we need a stargate though...
