That's like saying the UK banking system, the property market, stock market and other such investment based markets "wreck lives".
All sorts of ways to view things and for me it's pretty obvious (as I mentioned 2 posts ago) that if a retail client put £5k into equities and FX then traded daily for 3months you're not likely to be very successful.
If someone's going to go through and subsequently pass compliance checks to do the above then I'm not sure what to say. It's not a spur of the moment split second decision, its pre-meditated and with the risks clearly stated.
If a tier one bank, property company, or London Stock Exchange was in place of CMC would you be fine with that?
What firms would you want to see?
