Three bubbles; three crashes; the US, UK and Ireland are all now seeing their respective housing markets imploding.
Comparisons are always revealing. The US bubble was the most modest, peaked first and crashed furthest. The Irish bubble went higher, and turned downward about a year ago. The UK bubble went on longest, but it too, has turned south.
All three bubbles had the same underlying causes; credit credit, irresponsible banks, and greedy housing speculators.
