The issue of corporate profit margins in the United States

Corporate profit margins have been rising steadily for more than 20 years in the United States. This rise in profit margins is consistent with the growing corporate concentration in the United States (due to the proliferation of companies with dominant positions). The rise in corporate profit margins in the United States has not prevented: A decline in net corporate investment; A weakening of productivity gains; An increase in corporate debt. It therefore has no positive effect on the US economy, and obviously only serves to increase shareholder remuneration, and fits well with the monopolistic business model (higher profit margins, under-investment, low dynamism). Correcting the rise in profit margins is therefore a legitimate economic policy objective in the United States.
