It will take years for NPR and PBS to run out of money. You think they’ve been spending the billions they received from the federal government? Hell no, they’ve been stashing it in investment funds against a day like this. It will take decades for them to run dry. It will just slow them down a bit, while they weep and moan about how unfair a majority vote to defund actually is. What needs to happen is for the enabling legislation that created their charter needs to be rescinded as well.
It will take a lot longer than many think for them to collapse, but I doubt it will be more than 4 years. They may get enough of an increase in donations to survive the rest of this year without having to make changes, but they will soon enter a death spiral, as they also have a very high cost structure, as that 87 member editorial board is far from the only place they have bloated payroll.
