How did the corporations keep the prices from falling?

Corporations often prevent prices from falling through various strategies, such as maintaining control over supply and demand, implementing price floors, and engaging in collusive practices with competitors. They may also invest in marketing and branding to create perceived value, ensuring that consumers associate higher prices with quality. Additionally, companies can reduce production costs to maintain profit margins without lowering prices, while also leveraging exclusive contracts or patents to limit competition. By employing these tactics, corporations can stabilize or elevate their price points in the market.
