Yes, but buying power is determined by arbitrarily set prices and if consumers are willing to pay them.
But, despite “eating the cost,” executive salaries remain astronomical, or even increase, while employee wages remain the same, and mass layoffs are regularly made.
There’s just no validity to the idea that price increases are “needed” when the people at the head of the company have so much surplus money. They could cover those increasing costs. They choose not to because they value executives’ salaries more than laborers’ wages or consumer costs.
