I've never heard of him suggesting any actual wealth redistribution. I don't follow MSN at all, but I'd imagine by higher taxes they mean slightly more taxes on people making 6 figures. I don't care about people making only 6 figures. I don't believe Bill Gates is out there promoting policies that will relinquish his financial power.

Pipewire is much better than Pulseaudio, especially for pro audio work because of its low latency. Another popular option is JACK, which must be used in conjunction with Pulseaudio. Harder to set up, but is also great for pro audio. Some audio engineers were having issues with Pipewire when it first came out so they went back to using JACK, but I think Pipewire has improved. Pipewire has been flawless on my end.
If you're not in pro audio or any kind of multimedia work, it doesn't really matter and you can just stick with whatever comes pre-configured on your distro. But my vote goes to Pipewire as the best server for pretty much anyone.
