Look , lets look at one of those young couples Shawady and truthseeker are talking about. Bought a two bed apartment in 2006 for €400k. Today worth €160k if it could be sold. NE of €240k. Mortgage payment €2,000. He was working as an engineer earning €65k. She's a public health nurse, was netting about €2,700 now about €2,100 after tax increases and pension levy. He got a cumulative pay cut of 40% before being let go in Jan 2010. They have one child and she is pregnant. They had savings which they used to pay their way while he looked for a job. No luck on the job front (two of his friends got jobs doing bar work in 2009 because it paid more than they were earning at the engineering consultancy, but by the time he was laid off these jobs were much harder to find ) and they have now missed four mortgage payments. He went to a job fair in Dublin and has been offered a job in Australia earning €75k. She can earn good money their too and they are told they will qualify for permanent residency, and ultimately citizenship if they want it. So they have a way out.
So they can either rent the apartment (if its lettable) and send money home to top up the payment, knowing that the apartment will probably never be worth what they paid for it), or they can send the keys in the post and bet that the bank won't track them down. Which would you do? Knowing all that went on in the banking sector, in government, in the regulator, and the EU, would you still feel a strong moral imperative to pay the mortgage?
People like this example are still the lucky ones of course, because at least they have a choice. I'm more worried about the people who don't have any choices.
