We could always remove the charitable status of public schools.
We are also very charitable towards the likes of Tesco, Asda, Marks 'n' Sparks and a good few other big companies. They make massive profits,mostly predicated on selling junk and paying their employees as little as possible. The upshot is that thousands of their employees have to claim in-work benefits just to pay the bloody rent. Here's a fact: hardly any employee of any of said companies, if they were single, could afford to rent a flat or bedsit, let alone a modest house, on their income. We have to pay them benefits, which, when you think of it, are our subsidy to those greedy, useless companies.
