I know plenty of smart people that know a topic well and are still not great at simplifying it in a way that can be understood well by laymen. Separate skill imo

H1B isn't skilled immigration. Or at least it wasn't before this change. Thanks Trump!

>US tech companies still need mid-level workers making low-to-mid six figures

Yes, and there are plenty of US citizens to fill these roles.

I wasn't aware that we've already reached the end of 'work that needs to be done'.

Does this utopia come with four-day weekends?

Countries become wealthy because people in them work and make stuff. It's incredible to see people actively advocating for making their country poorer. "No, no, we have too many people working..."

The entire point is to block middling unneeded H1Bs that are just taking middle-class American jobs, a high yearly salary bar does exactly that.
