As jhegarty already mentioned, this is exactly what caused the credit/debt crisis, if anything the ICB rules should be more stringent. Some people should not be given loans; this may sound unfair, but the alternative is now evident.
Also, people are in financial difficulties because of their own doing, not through the fault of others. If you take on lots of debt you better make sure you have provisions made if your income changes. Having too much debt that cannot be repaid as soon as your income is adjusted can be blamed on noboby but the person taking on the debt.
