Man, here’s the thing. He paid his taxes right? Did Elon paid around the same amount his net worth? Did any other billionaire did?
Now, remember those people seeking clout using charity? What if more people seeking clout using charity? What if more billionaire seeking clout by paying taxes too? Sure, not “good” or “perfect”, but better. As in, 1 is better than 0 because something is better than nothing. But I’d argue that something better is a good thing in general.
Would you like me to give you some money to help your debt, but not in full or none at all? Same thing here, only the debt is to society in the form of taxes. Something is better than nothing and hence a good thing.
