Someone just posted the actual wsj investigative article. But saying the daily mail is a right wing rag is missing the reality that all the news outlets in america, all circularly owned by the same multi national war profiteer interests, are all right wing rags. Some of them just pretend to lean left when they are center right at best and unfortunately a great deal of people are naive enough to buy their bullshit.
There is no law mandating that charities have to give any specific amount of the money they collect which is why many charitable organizations can get away with siphoning as much as they they can to executive pay and administrative costs 5-15% may be a lowballed generalization there are likely some people in these roles who do better. Red cross claims 90% goes to the cause but thats highly unusual. There are 42 different charitable non profits in the us where their ceo alone is paid over $1,000,000. The ceo of the sloane kettering cancer research center, Selwyn Vickers earns an annual compensation of just over $5.7 million. Now thats not much for a charity that takes in 7.3 billion but i would be surprised if more than 1.5 billion of that actually went to cancer research My favorite argument against charity is by Slavoj Ziezek who argues that charity demoralizes and degrades it is immoral to use private property to alleviate the issues caused and exacerbated by private property society instead needs to be reorganized so that poverty is impossible.
Here is some good reading on how the system of charitable non profit organizations is abused bh the wealthy to further enrich themselves
