Whit all due respect
Each one is responsible of its own finances, If Billy's parents have a loan and many debts , If they didn't have an emergency plan and cant afford to survive in Dubai for 1 year with no income, then maybe they should consider other options, selling a property ? selling cars? Resigning? I'm putting myself in that position, I will sell a property to cover my expenses for 1 year before asking other people that also have debts and responsibilities to cover my own.
My 2 cents
