Stop trying to justify what is wrong. You lose 100% and get 18% tax relief is fine. Tell you what. Lend everybody $1000 each then write it off.
Ok let's get technical. YOU lend MONEY to TAN AH KAU, He needs to pay. HE PERSONALLY LOAN IT from you, NOw you LOAN IT TO TAN AH KAU PTE LTD, likewise TAN AH KAU PTE LTD need to pay, GO after the NAMED company, sue it wind it down for all the world cares. But going after the directors, ex-employees is unscrupulous! You are "STUPID" enough to LOAN to TAN AH KAU PTE LTD for a profit in return so you are not a saint either. YOU took the risk, YOU bear the consequences of delinquency if any. SO you expect the HIGH CODE of CONDUCT or morality from the credit given, but you do not expect the same measure from the creditor?
all you have done is avoid being right about the issues, but choose to demonize those who didn't pay.
SO in the same light, LOAN SHARKs is a GLORIFIED profession in your perspective.
Instead of saying welcome to the real world, I would say to you, please STEP out of your UNREAL MORALITY HIGH world and really really step into the real world.
The corporate law is a double edged sword. It protects the real defaulters in business as well as the "con" defaulters. Likewise for bankruptcy - some even know of the loopholes in bankruptcy law and go around getting loan then bankrupt then using the loopholes for discharge then get out again to get more "Loan"! I heard of REPEATED bankruptcy individual. SUch is the REAL world my friend. Ugly but true.
