To answer the OP’s question, Labour’s definition of “the rich” is anyone who is a high rate tax payer – despite the fact that now includes many nurses, teachers and other roles historically viewed as underpaid.
With earnings well over the threshold for 40% the OP is in fact too well off and without realising, part of the reason there is inequality in the UK.
The OP should vote for Ed if he wants to make up for his pariah like status because Ed knows how to spend your money better than you do – even if that means most of it in reality will just be wasted – which is precisely why Labour introduced the tax credit system to ensure that families on benefits can receive the same income as the OP’s net wage without actually having to work.
