They could afford a ticket to go in the first place and as I understand it, entry into the US and most countries as a tourist, requires a return ticket.
If you are travelling to the US and Europe you understand (unless you are real dumb, stupid or both) it aint going to be done on the cheap.
Let them use Visa, Mastercard, garnishee their wage or put them to work to earn enough to pay for thier rescue.!
Why should the taxpayer keep supporting people who refuse to accept resposibility for their actions.
