I already illustrated, feel free to reread my post.
Its basic economics, if you give a poor person money, they will more then likely spend it somewhere, so its funnelled back into the economy. That person may spend it at your business which means its £48 more turnover for you.
Its basically only their money temporarily.
But poor people who work won't be any better of!
All you have done is incentivise people not to work!
Why don't we give the poor a million pounds each to incentise them to spend by your logic?
