It's anything but clear although I think a self-appointed group assures us they know what's best despite tolls being wildly unpopular when real people are asked.
No pretty much all real-world evidence points to them being positive [0]. Feel free to share evidence otherwise, if you have any.
You can argue about popularity if you want, the topic is actually about whether they're "in the public interest" though. Those are distinct things, and "I don't like them because they're unpopular" is pretty hilariously circular logic -- not the type of thinking I'd want my name attached to, that's for sure!
"If presidents could be prosecuted for their official acts"
This has always been presumed to be the case yet it has never resulted in what you say. It's a nonsense theoretical as cover for what is otherwise utterly indefensible as making the president king.
