It's a chicken and egg issue. Webcams are crap partly because nobody has a good upload bandwidth to make it matter. Video software uploads at low bandwidth because everyone's connection is crap, etc, etc.
Also more than one person lives at a household typically. Imagine 3 or 5 zoom calls going at 4mbps simultaneously. That's 20mbps right off the bat, which over saturates most people's upload, so zoom goes conservative by default.
Or imagine in a remote learning, you could see the pupils laptop screen , their desk and their face simultaneously so you can help them with their issue quickly, in 60-30fps HD+ per stream. And then do that for 3 kids + 2 adults and now you have 60mbps. For the adults, simultaneous face, desk & slides would be a form of seamless white boarding at a presentation.

Many applications are limited by shitty internet.
