To understand how this situation has come about have a read of "Red-Handed" by Peter Schweizer.
The Chinese "elite capture" program is well-documented. They intentionally ensnare govt & business elites (and family members) in extremely lucrative deals with China to ensure they remain pro-China's interests. And there are some big names in there (Bidens, Pelosi, and McConnell etc).
The media doesnt talk about this corruption as they all have movie studios and want to sell their movies into China.
Its why there may be occasional discussion of the problem (like here) but for some inexplicable reason, simple and obvious steps are never taken.
The political will simply isn't there due to elite capture IMO.
