Finally, someone with a brain. Be forewarned, last time a discussion like this existed the EMA huffers only response was "you're jussss jealuz" - though it may be true, it doesn't account for the fact the system is lousy and in need of a change - if not scrapping at all! A complete overhaul is needed to account for people who definitely do not need it with the people who do, and a way so that it is only used on what the EMA say it should be used for e.g. transport and equipment. If you're not using it for that, you shouldn't be getting it at all :/
Besides, if the people who do use the EMA are worried, then they've got something to hide. Having a system where you don't get money handed to you, but a sort of "free bus/train passes or equipment" system, or even a debit system, would not effect people who use EMA correctly anyway.
I have had friends who are receive EMA, and they used it correctly most of the time, but everyone lacks self-control, so they will naturally be tempted to spend it on something else - they're only human and money is money, you cannot physically seperate money into different categories or uses, it is spent any way possible. It's the system who is at fault, not the people :/
