I would argue that we abolish things like the BBC license, allowing politicians et al. to give themselves huge raises, sending funds to various countries for aid that has never helped, and so on. We could funnel that into those schools and what not.You have no idea what level of expenditure you would be agreeing to. And you do not speak for everyone who pays tax.
If Bozo were to announce a huge programme on maintaining all the empty parish churches, the outcry would be immediate and from all sides: "How many people die every day in the NHS that could be saved with this money?" "What about collapsing school buildings?", "Why isn't this being spent on the police, to prevent another Sarah Everard murder?" etc., etc.
And those questions would be rather good ones.
In Britain the state does give grants for the upkeep of buildings of outstanding historical or architectural significance, and that keeps most of our great cathedrals from falling down. But there has to be a limit to the largesse.
Charity starts at home, essentially.
