These claims are quite hard to square with the long waits for H1B visas, extremely high salaries in the technology sector and net immigration to the US from China.
I’m not aware of any Americans or Europeans in my network who have gone the other direction to China.
Perhaps you have different data about the demand for tech worker visas in China.
EE as a US career is night and day from Software centered engineers. Night and day from 20 years ago as well.

I don't think it's much of a controversial take to suggest that China is kicking the US's butt in silicon chip production. EE's are one of the primary fields traditionally seeked to work with this.
That will be controversial until mainland China produces modern process chips economically (they can do one or the other so far). Rather Taiwan and South Korea are not the EE powerhouses. China though pays better than Taiwan (a lot of the hardware researchers in my Beijing lab were from Taiwan and Korea).
