This is hilarious.
Your family presumeably earns at least £30 more per week, than the families of those getting EMA.
As such, you don't need EMA.
Claiming that all EMA goes to lowlifes is $%ing insulting, that's literally saying all people who have less than £30k per year income, are low lives.
I have close friends who I didn't even know earned EMA, since they were embarassed about their family incomes (which they ought not be) - I wouldn't be suprised if you had the same.
I don't get EMA either, but I've never met anyone truly bitter about not getting it. I'd imagine that your parents can afford to give you £30 a week, but choose not to, assuming that you don't NEED £30 a week.
That's your parents' call, and not something you should take out on those worse off than you.
