Nanadeturbe " it's wrong to store (hoard) money that will never be used while fellow human beings are in need. " Money is an inert thing. only of use for what it can buy. Taken from one person and given to someone else it will cover their needs at that moment, but it won't support them this time next year, or for the rest of their lives. That will need a repeat, and a repeat and a repeat.
A good government oversees the economy and the infrastructure so that every child gets as good an education as the most affluent ( but doesn't assume that every child is identical to all others and will come out of a sausage machine identical to all the other links - nor would it be a good thing if they did) has easy access to medical treatment as good as any that the rich pay for, that the legal system is as accessible and fair to the shelf stacker as to the tycoon, and that all other organisations of the civilised state work for the benefit of every member of the population.
To do that takes money. The state has no money of its own, only what they get from the population through taxes. The tax structure is such that those with the biggest income should pay the most tax. If more money is needed to fund all the infrastructure, then it has to come either from taxes or from persuading the wealthy to endow more schools and hospitals etc.
You can't stop people from making money and putting away the surplus for a rainy day - that is the same instinct as our distant ancestors had to collect wild food when it was plentiful and store it, or to grow more produce than they could eat immediately and preserve it for winter. what you can do is to make absolutely sure that some of their stores go toward funding the national organisations that support those who don't have a big bank balance.
Perhaps, encourage the philanthropic to endow a school or a hospital ward and continue to pay all of its expenses. Some old schools and hospitals were set up centuries ago with buildings and a capital investment whose interest brought in an income, specifically for orphans or the poor. Part of the motive was to make sure that the donor would have a seat booked in heaven, but the earthly result was that education and medical care wre provided for some, at least, of those who would not otherwise have received them.
Philanthropy is not a fashionable concept these days, any more than honourable and imaginative public office.
Sorry this got so long.
