I left Ireland in 2007 at the height of the economic boom there, the unemployment rate was under 5%1, house prices had gone through the ceiling and the head of state had suggested that anyone who thought there might be an end to the boom should go and kill themselves. I passed through Philly in March 2008 and the news from back home was not so good as the international banking collapse was having its impact. That June I moved back to Ireland, and from then on the economy went into free fall, pushed over the edge by property speculation, which had grown exponentially in the previous decade.
