They’re breaking their own ponzi scheme economy for a few more quarterly profit boosts because there’s nowhere else to grow/metastasize. Media companies are making less media. Food makers are making less product types. Their profit is coming out of gutting workers and their ability to produce what their economic sector produced in the first place.
This is a terminal stage market capitalism fire sale. The snake is eating its own tail having conquered the board.
