Just know that terms like "diversity hires" or "DEI" are supremacist dog whistles. I'm referring to the two comments above. This is how supremacists explain to themselves why there might be brown and female faces within a sector or in positions of power/high visibility.
There's actually an answer to this. Companies will just keep globalizing their customer base even further, turning increasingly to other markets outside domestic ones to keep afloat. For example, if you look at Hollywood, you'll see that our movies are no longer made for American audiences but foreign ones and are even being bankrolled by foreign companies.
All Americans have to do is lobby to get them broken up or stop giving them so much spending power. Instead of boycotting and lobbying, we're handing all of our money to these companies and, to make matters worse, letting them get away with murder (tax fraud, bailouts, etc.).
