Ending it suddenly without a replacement would be a catastrophe, no doubt about it. That doesn’t mean they deserve tax exempt status. The majority of charities are pretty decent and get a good portion of their donations to people in need but there are also charities that are basically a way for the wealthy to avoid taxes. I think the government will better represent the will of the people (in normal times), have lower overhead, work faster, and close the loopholes. I’d also be satisfied with closing the loopholes that allow people to take advantage and avoid paying taxes. Donating a few million to the charity you own to get a tax break, while your nephew runs the charity taking a fat check, and makes the area you live nicer; improving your real estate values should not be a thing.
