There are actually very few "Booming Economies" simply because when you look at 7+ years of zero interest rates what you have are more along the line of completely false economies. Rates have started to go up in the US, EU and Asia will not be far behind, a couple of hunderd basis points will make a huge difference.
It will all be very different if people have to actually pay for money rather than getting it for free. No one ever wants to think things are going to go bad, hope is eternal but doesn't pay the bills.
