Why is the corporate income tax so high in the United States?

The corporate income tax in the United States is one of the highest in the world. This tax is imposed on corporations and businesses to generate revenue for the government and to promote economic growth. The current federal corporate tax rate stands at 21%, which is higher than the average rate of other developed countries, such as the UK and Germany. The US also has state and local taxes which add to the overall burden on businesses. Furthermore, the tax code is complex and has many loopholes, making it difficult for businesses to comply. All of these factors contribute to the high corporate income tax rate in the US.
