You don't understand how money works.
They are not burning money, they are employing people like you directly or through 3rd party partner companies. The beneficiaries can decide themselves how to spend money. They can live a good life or help others.
Ah yes, they're just redistributing the money, the trickle down economy right ? They're basically a non profit humanitarian association at that point
Still living in the 80's?
Seems like you are the one with an outdated model of how money works.
Over the last couple decades it has been moving up at an ever increasing rate instead of down.
Money buys labour. That labour could be in service to ending world hunger. That labour could be in service to creating bullshit. Both approaches leave workers with money in their pocket, letting them engage in that game of prisoners dilemma we call charity.
